Based on:
* https://github.com/weechat/weechat/issues/1383
<https://github.com/weechat/weechat/issues/1383>
it is likely that the Python library on that system should have been linked
with -lutil, but Apache (which is the main program in this case) isn't.
Further, the Python distribution configuration is not properly setup to ensure
that library is linked when building C extensions.
The quick solution may be to find where libutil.so is located (possibly
/lib64/libutil.so), and with the correct path, add a line:
LoadFile /lib64/libutil.so
just before the LoadModule line for mod_wsgi.
