Looks like libwmf contains its own private copy of libgd, BAD! BZ please.

Looks like these contain a private copy of libltdl, BAD! BZ please.

Looks like libgs contains a few private copies of libjpeg functions,
these should be checked to see if they are different from the libjpeg
ones and if different they should not be exported and if not different
they should be removed and the libjpeg ones should be used.

Looks like libopal_linux_x86_r.so.2.2.2, contains its own copy of speex,
bad BZ please.
