As far as I know we installed a binary package from some site, don't
from where exactly, though. However, in xml/parsers there is expat.py
but no pyexpat.

It shows the same behavior for both 0.6.2 and 0.6.3. 'uname -a'
says 'SunOS kazul 5.7 Generic sun4m sparc'. I just tried to recompile
the package on a more recent machine (SOS 5.7, but type sun4u instead
of sun4m) and this one seems to work (on both machines!), I can create
an Expat after installing the package. Strange, but anyway.

Now, that's indeed confusing! With this hint I could quickly trace the
problem down.

Thanks for your quick help,
