I\'m having difficulties updating RubyGems from version 1.1.1 to newest. I\'ve tried the following:
gem update
Result:
Oi - I feel your pain. I'll first ask the obvious; Have you been executing the commands with sudo? So you'll use sudo gem install rubygems-update and sudo update_rubygems.
If that doesn't work, download gems source again and rebuild from scratch (may want to erase prior source download, etc). You may want to read HiveLogic article on installing Ruby, RubyGems, etc on Mac OS Snow Leopard.
If that doesnt' work... :) I might do the drastic and rebuild Ruby as well.
