Sadly it only gets us part of the way there.  Other files, besides
manpages pop up.  /usr/bin is a common one, but easily dealt with.
The real scary one is /usr/share/doc -- the files aren't in the
buildroot when %install is being run!  RPM places them there later.
This is difficult to avoid short of ignoring the local policy and
redefining docdir or somesuch... which I am not totally in favor of.
The net result there is although you could still perhaps override core
perl modules with these kinds of RPMs, you can't really install two
concurrent ones (ie, perl-Foo-1.1 and perl-Foo-1.2) since they would
conflict over docdir.

RPM-Specfile-1.19 is being uploaded to CPAN tonight.  It contains this
change (--use-usr-local, horrible name, alas) as well as the code to
detect the name of the top level tarball.

Please give it a whirl!

Thanks,
Chip
