Hi, A few weeks ago I tried to install fxruby, went grey, ended up installing fink and darwinports, lost more hair and ended up completely trashing Ruby on my (wife's) system here. Thanks to some good advice on this list (yes, I brought 'Learning unix on OSX Tiger - good book btw), I was able to get ruby up again. Which brings us to today, when I decided to try fxruby again. Agghhh... still no joy, but this time, before I mess thing up I though I'd ask for some advice. All I've tried this far is installing via gem. Here's the result: mac:~/Documents sharon$ sudo gem install fxruby Select which gem to install for your platform (universal-darwin8.0) 1. fxruby 1.6.11 (ruby) 2. fxruby 1.6.11 (mswin32) 3. fxruby 1.6.10 (mswin32) 4. fxruby 1.6.10 (ruby) 5.
