src/main.c and src/ui.c include libgsm/phonemgr-utils.h that in turns includes <gnokii.h> but src/Makefile.am doesn't use LIBGSM_CFLAGS so this works only if gnokii.h is installed in a directory searched by default by the compiler (like /usr/local/include and /usr/include).

Expected behaviour is not to include gnokii.h indirectly because main.c and ui.c don't need it.

Output showing failure to find gnokii.h (libgnokii was installed with --prefix=$HOME and gnokii.pc was copied where pkg-config could find it):
