So, libgphoto2 has ugly pile of macros to check for libs. It first tries pkg-config search for libgd that fails because we don't ship any libgd.pc. Then it tries gdlib-config and treats that as regular *-config script. But... $ gdlib-config --libs -lXpm -lX11 -ljpeg -lfontconfig -lfreetype -lz -lm Notice no '-lgd' there. So 'gdlib-config --libs' outputs only libs needed for static linking. libgphoto2 assumes '-lgd' is supposed to be there and fails to link the test program.
Possible hack-around: LIBGD_CFLAGS=" " LIBGD_LIBS="-lgd" to econf. Still worth reporting upstream though.

(In reply to Michał Górny from comment #0) we follow what upstream does. gd-2.0.x didn't ship a .pc file. the new gd-2.1 includes it, but that isn't yet in the tree.
