UPDATE: Just selfupdate MacPorts if it isn't showing R12B (which is now released) and update erlang instead.
UPDATE: I have rewritten this article after reading Jim's comment on how to set up a local MacPorts repository.
Since there is not yet a Portfile for Erlang R13A in MacPorts I built one myself. MacPorts makes this remarkably easy since the Portfile format is so easy to read and write.
Save the following as ~/Desktop/Portfile:
# $Id$
PortSystem 1.0
name erlang
version R13A

description The Erlang Programming Language
long_description \
Erlang is a programming language designed at the \
Ericsson Computer Science Laboratory. Open-source \
Erlang is being released to help encourage the spread \
of Erlang outside Ericsson. \
\
We are releasing free of charge: \
The entire source code of the current Erlang \
system. \
Extensive libraries of code for building robust \
fault-tolerant distributed applications. \
All with documentation. \
\
All the above software has been battle tested in a \
number of Ericsson products, for example the new \
Ericsson ATM switch.

Save the following script to ~/Desktop/mkerlangport.sh:

local_repo=/opt/local/var/macports/sources/local
sources=/opt/local/etc/macports/sources.conf
port=lang/erlang
cat ${sources} | grep file://${local_repo} > /dev/null
if [ ! $? ]
then
tmpfile=`mktemp -t sources.conf`
cat ${sources} > ${tmpfile}
echo "file://${local_repo} [nosync]" | cat ${tmpfile} > ${sources}
fi
mkdir -p ${local_repo}/${port}/files
cp ${macports_repo}/release/ports/${port}/files/* ${local_repo}/${port}/files
cp ~/Desktop/Portfile ${local_repo}/${port}/Portfile
portindex ${local_repo}
Run this script in terminal as sudo bash ~/Desktop/mkerlangport.sh. It should report
Creating software index in /opt/local/var/macports/sources/local Adding port lang/erlang Total number of ports parsed: 1 Ports successfully parsed: 1 Ports failed: 0
Once you have created the Portfile and installed it as instructed above you can sudo port install erlang @R13A +smp +ssl to get R13A. If you have R12B already installed you should sudo port deactivate erlang first. I am not sure if upgrade works since I haven't tried it.

Ack!
Do not overwrite the rsync.macports.com portfile! Create your own local repository. Add the following line to /opt/local/etc/macports/sources.conf ahead of the rsync line:
file:///opt/local/var/macports/sources/local/ [nosync]
and then do the following:
mkdir -p /opt/local/var/macports/sources/local/lang/erlang/files
cp /opt/local/var/macports/sources/rsync.macports.org/release/ports/lang/erlang/files/* /opt/local/var/macports/sources/local/lang/erlang/files
cp [erlangR13A-portfile-path] /opt/local/var/macports/sources/local/lang/erlang
portindex /opt/local/var/macports/source/local
You will now be able to do the port upgrade and when the macports tree updates with a new version you will not have your changes stomped on by the new portfile. You can also now start using your local macports repositry to create portfiles for projects that are not currently in macports (I do this for a lot of erlang projects that are out there) or create your own variations to existing ports.
@Jim:
I cannot MacPorts to install R13A now. It keeps installing R12B even when I specify the version in the install command as install erlang @R13A +smp +ssl.
When I run info erlang from the port shell I get the following output:
Warning: Found 2 port erlang definitions, displaying first one.
erlang @R12B-5, Revision 1 (lang, erlang)
Variants: i386, no-hipe, smp, ssl, universal

I know I am doing something silly. Is there a simple way to fix this? I would rename my Erlang port to erlang_exp to disambiguate it, but I am worried that will cause weirdness since it installs to the same place as the erlang port.
I figured it out. The order of sources defines the precedence of ports chosen if duplicates exist. Putting the local source second means (in this case) that its ports will never be installable. Putting it at the top of the file works.
I have a slightly different portfile at github that supports hipe (with 32bit erlang - working on patches for 64 bit), working ssl, odbc etc.
The 64bit variant currently produces a working erlang, but wx (and possibly some other libs) doesn't compile properly.
