The problem is (which was discussed on git mailing list) that gitweb
is to be run on servers. And admins are very reluctant on putting
anything but well tested software on server. The order is: in standard
installation, in core distribution, in extras package of distribution,
in trusted extras repository... random CPAN package is usually out of
the question.

True.
BTW. I have thought that we already require libwww-perl with the
modules we use in gitweb, but they are all packaged with Perl.
While I don't think that there would be many complaints requiring
libwww-perl, I'd rather have it optional...
