IIRC, in Python 2.6, it was possible to get the building of hashlib 
confused when building Python.  Basically, at build time, it tries to 
find openssl and build hashlib to link with it.  If it can't find the 
openssl lib, it builds its own versions and that's what _md5 is supposed 
to be.  But sometimes it could get it wrong but I don't remember the 
exact sequence.  Possibly one way could have been a conflicting version 
of openssl in /usr/local/lib,

However, you should be able to get it to build and work properly (among 
other platforms, I have it on a G4 running 10.5).  I'd suggest the 
following steps:

First, check to see that you don't have a version of openssl in 

ls -l /usr/local/lib/libssl*

If you do, figure out if you really need it and either delete it or 
rename it out of the way before going on to the next steps.

sudo port selfupdate
sudo port -f uninstall python26
sudo port -f uninstall openssl
sudo port install openssl
sudo port install python26
