Hmm, I'm confused: On both stable and unstable installations here, libgd
seems to have a dependency on libpng12. Furthermore, nothing seems to be
using libXft, running lsof over a running slimserver process shows
libfreetype and libfontconfig, no libXft.
Are you sure that your libgd installation isn't "strange"?

This way out of my pay grade, I'm afraid. I can push it into upstream
Bugzilla if you like (I've done that with the patches you supplied, as
well as applying them in Debian) but it might be better if you did so
yourself; the better to answer the inevitable queries.
