I know, I'm trying to pay somebody this spring to write me one!

OK, for a start PyDSTool has not been tested at all on Python 2.6. I
just haven't been able to keep up! If there's any chance you can also
have 2.4.3 or 2.5 on your system then that would be the easiest thing
to do. I know that people have installed successfully recently from
SVN on Python 2.5. Maybe I need to post a clear disclaimer on my
webpage since Python 2.6 has become so common.

I don't have a clue right now.

The list of test failures you sent me is pretty catastrophic, which
makes me suspect the problem is something basic in python that has
changed between 2.5 and 2.6 that is at the heart of every one of the

And/or it's something to do with Pyrex getting involved for the legacy
ODE solvers. I don't know why the pyrex compiler is being invoked,
because it should be gcc. Can you look at the wiki GettingStarted page
(Section 1.4.5.) on getting C integrators set up on Linux and tell me
if you've set up SWIG and set the CC environment variable?
