Do not patch Makefile.in, patch Makefile.am and rebuild autotools, please.
This package wants antique automake 1.4, which is not normally emerged eny more. Yet it works (with a few warnings) with latest automake, too...
Should I hard depend on automake 1.4, or I go with latest version?

Fixed as new package revision.
