+Here is a patch for adding pkg-config support to libmad.
+It would make life a bit easier for distro maintainers if this was applied.
+In case you didn't know, pkg-config is a tool for providing LDFLAGS and
+CFLAGS for packages using shared libraries. It's on freedesktop.org.
+Debian has already been distributing the pkg-config file mad.pc with
+libmad for some time, and people developing on debian (notably xmms2
+developers) have started relying on this support being present, causing
+some confusion for people installing from source and on some BSDs which
+do not provide mad.pc (google: pkgconfig libmad).
