Paul Traina 1dd5e27809 Test test test! sigh!
Perl's scripts are still trying to execute perl out of /usr/gnu/bin/perl.

The hack Larry was using for h2ph.1 doesn't work with the new macros, so
make it a real man page.

Also, we weren't building the .ph files, add them as an afterinstall rule
in the x2p subdirectory.
