You can only have one symlink for /usr/local/bin/python  Other than  
that the two installs coexist just fine.  The real problem is the  
random py-whatever ports.  They select which python install to use  
based on PYTHON_VERSION, which is python2.5 unless overridden.  The  
problem comes when they don't drop everything in /usr/local/lib/ 
pythonX.Y/site-packages, but rather go in to /usr/local/bin or whatnot.

So the procedure I generally use is, install python 2.5, install all  
my py-whatever ports, install python 2.6, then set  
PYTHON_VERSION=python2.6 n /etc/make.conf, then go back in to the py- 
whatever port dirs and do a make clean install - 
DFORCE_PACKAGE_REGISTER  This needs some testing on your part to  
ensure the ports don't overlap or scribble on each other.  Hand  
mangling may be needed, or better yet, install the two versions in  
different jails or chroots.
