I recently upgraded to Lion and everything was fine. Even rebooted the machine a few time. Then over the weekend, Rails was gone! All of my gemsets were gone. I swear I don’t know what happened. It WAS working just fine.
After looking closer, RVM itself was gone.
So, I reinstall RVM and try to install Ruby 1.9.2 and I get this error log:
[2011-08-08 14:30:41] ./configure --prefix="/Users/cbmeeks/.rvm/usr"

configure: error: in `/Users/cbmeeks/.rvm/src/yaml-0.1.4':

See `config.log' for more details
It appears that gcc is gone? I’d prefer not to just start randomly reinstalling everything since all was working before.
Any ideas?
Thanks.
After you install Lion, you have to re-install Xcode/Developer tools. It is available from the app store.
