Sure it is not CPAN problem. But I might solve future failures (if any) by having local::lib in git repo.

While testing/develpoing, I can see that libX ver.123 got memory leak/bug/etc. So I push to local::lib ver.111 that has no problems. In this way - there is no need to install ver.111 manually on multiple servers. Just pull, everything from git repo, that was tested, and confirmed to work previosly.
