I\'m having a lot of trouble getting Ruby 1.8.7 installed on my clean install of Mountain Lion. I\'ve looked around on Stack Overflow and don\'t see anything that specifical
I just figured it out! Please reference this question on SO
rvm can no longer install 1.8.7-p352 on Mac OS X Mountain Lion
rvm reinstall 1.8.7 --without-tcl --without-tk
Alternatively, try this installation order if you have Homebrew.
brew install tcl-tk rvm reinstall 1.8.7
