It's
use lib "$Bin/../lib";
(I don't like this ../lib here, but that's my personal preference).
But you might be right that I am overly cautious in avoiding FindBin.
It is nowadays not recommended solution (on #perl, for example), but
it is perhaps true that the conditions where it fails are not fulfilled
for the case of gitweb.
Or perhaps not:
KNOWN ISSUES
If there are two modules using FindBin from different directories
under the same interpreter, this won't work. Since FindBin uses a
BEGIN block, it'll be executed only once, and only the first caller
will get it right. This is a problem under **mod_perl** and other
persistent Perl environments, where you shouldn't use this module.
Gitweb can be used under mod_perl (to be more exact ModPerl::Registry).

Ooops, I'm sorry.
I'll fix it in resend, if required.
