Mmm, I'm not sure if I got it.

My gobolinux.pth currently looks like this:

/System/Links/Libraries/python2.3/site-packages/
/System/Links/Libraries/python2.4/site-packages/
/System/Links/Libraries/python2.5/site-packages/

Are you suggesting for it to look like this? (paths mixed with Python code?)

/System/Links/Libraries/python2.3/site-packages/
/System/Links/Libraries/python2.4/site-packages/
/System/Links/Libraries/python2.5/site-packages/
import site; site.addsitedir('/System/Links/Libraries/python2.5/site-packages/',set())

In any case, if I do this, I get:

'import site' failed; use -v for traceback

everytime I launch Python. Running 'import site' directly from Python
gives me a long stack trace, with the error:

RuntimeError: maximum recursion depth exceeded

I tried removing the other paths from the file, and clearing the
$PYTHONPATH variable, but I still get the same error. Does anybody
have any idea?
