kdevelop creates a /usr/kdevbdb/ directory, why? it seems to keep db_* files only. can't it merge in /usr as normal packages?

This should be asked to the kdevelop developers at http://bugs.kde.org, that directory is part of the default "make install".
i added the request in this bug http://bugs.kde.org/show_bug.cgi?id=109753
