[Chimera-users] new version available

[Charlie Moad]

Also, here is a case scenario.  I can build matplotlib
(matplotlib.sf.net) with the following command:

CPPFLAGS="-I/usr/include/python2.4" /usr/local/chimera/bin/python2.4
setup.py install

I have python2.4.2 installed, so I just use those headers.  This
works.  Now when I try to use matplotlib I get an unresolved symbol,
"PyUnicodeUCS4_AsUnicode" from one of its shared libraries.  This
symbol is located in libpython2.4.so, which is not in the chimera
bundle.  I can work around this by launching chimera with:

LD_PRELOAD="/usr/lib/python2.4/config/libpython2.4.so" chimera

This is obviously a temporary work-around.  I would hope windows won't
be this complicated.  Any suggestions on how to better address an
issue like this?

Thanks,
    Charlie
