#15 fails to build with ld --as-needed
the use of automake and pkg-config is wrong leading to a build failure with the linker flag --as-needed
the pango libraries are added in LDFLAGS but they should be in LDADD
this requires proper use of pkg-config via PKG_CHECK_MODULES in configure.in
attached a patch which fixes this issue.
Another related issue. libpaps.so is underlinked leading to problems when linking other programs to it with as needed.
