I see -- in that case, gitweb.perl should indeed be fixed.

Still however, for the Perl tests (t/t9700/test.pl in my branch) we 
don't have a Makefile, so the only way for them to pick up the right 
Git.pm module is modifying PERL5LIB in test-lib.sh. [1]  I just realized 
that we not only don't need to set GITPERLLIB in this case, but we 
should actually unset it so that user-set paths don't cause a wrong 
version of Git.pm to be loaded.  I'll send a new patch.

[1] Or alternatively adding some (lengthy and cwd-dependent) "use lib 
..." statement at the top of every Perl test file, but that doesn't seem 
preferable given that we can solve this centrally in test-lib.sh.
