It was a problem in otherwise very successful perl's CPAN. I don't recall any "dramas", but because of a huge number of dependencies installing Catalyst had a low change of going right the first time. But! Because of the test everything culture and CPAN testers effort broken modules were very rare. So after you managed to set up your system and had a long walk while tests would run it was guaranteed to work. More or less.
