That's a good point, Kevin. We need to make sure that he's trying to start sigil only after installing it (make install), and that he's launching it with the recommended /usr/local/bin/sigil launch script.

It sounds as if he could be trying to run sigil without it's full complement of support files (/usr/local/share/sigil). Like maybe a partial, broken, or altered (after compilation) installation.
