Most of these are probably indirectly dependent, and may not be
seriously affected. Many, for example, may have been dragged in by
xorg's silly dependency on python via libxcb.

As the others have mentioned, you don't need to do this unless you
wish to use a version of python other than 2.6, which is now the

1) See above.
2) I didn't mean, as Seaman seemed to think, and you may have, that
you can use ports built against 2.5 with 2.6. That would only rarely
work, and most likely lead to all sorts of problems. Instead you
should proceed with your plan, and rebuild all dependent ports via:
portupgrade -fvrx lang/python26 lang/python26
rm -r /usr/local/lib/python2.5
or rebuild just that subset of ports that are most likely to be broken
by the change, via the upgrade-site-packages target in lang/python, as
What I meant by my original comment was, that if you should happen to
want to build a port against 2.6, but find that it is hardwired in the
port Makefile via USE_PYTHON to another version or versions, and you
don't want to go to the trouble of patching the port Makefile, and
then preserving this local modification when you merge in updates to
the port tree, you can add a workaround in /etc/make.conf. Say, for
example, you see that mail/py-spambayes has:
in the port Makefile, and you want to install spambayes, but you don't
want to have to reinstall python 2.5 or an earlier version of python.
If you add:
to /etc/make.conf, you can override the spambayes port Makefile
without patching it. Now, you are _not_ supposed to do this, and you
will probably have to deal with any consequences of such a local
change on your own. Many ports have these restrictions for a good
reason, but such an override can be occasionally useful.
