Cleaning out macruby (if you have to)
Macruby 0.6 is out, and with it a lot of new enhancements, but unfortunately i’ve been having some difficulties with rubygems.
Thankfully Matt Aimonetti is not only an awesome guy but also willing to help out if you’ve got a problem! I asked him what i could do to get my system back to a pristine state (since running the installer again over my borked install didn’t help).
Matt pointed out that all macruby really does to your system is drop some executables into /usr/local/bin/, and a framework in /Library/Frameworks/MacRuby.framework/.
So, if you do this:
ls /usr/local/bin/mac* | xargs rm
rm -rf /Library/Frameworks/MacRuby.framework
(you may have to sudo for the last one), you should be back to square one from which you can reinstall macruby.
Happy hacking!
