We are need *doc* USE flag, or/and add *help2man* dependency.

This breaks stage building when this version of libtool gets pulled in. Please fix the package to not need help2man and feel free to drop the dep at that time. For now, I've added the dep so it builds.
2.4.3 isn't in the tree. assuming current stable is fine.
and we know the latest doesn't work -- see bug 556512
