Oh, yeah, I've been through them many, many times. I keep running into cascading perms problems - fix one and 3 more rise up to take it's place. I haven't had anything to do with perl - well after my time in the industry - and I hate, hate hate the way it automates all the installs. Frankly I'd rather do it by hand so I could have a much better understanding of what's going on. I do better with the "make sure you have read perms on blat" kind of approach rather than blindly following the "now type 'chmod +r blat'" kind of instructions.
