I had Xcode 4.1 preview 5 working fine but decided to upgrade to the final xcode 4.1 thru the App store. I uninstalled Xcode first...
sudo /Developer/Library/uninstall-devtools –mode=all
Then installed Xcode thru the app store and rebooted.
I also removed RVM completely but... now whenever I try and install a version of Ruby it fails. In the error file i get this:
[2011-07-27 18:29:25] ./configure --prefix="/Users/holden/.rvm/usr"
checking for a BSD-compatible install... /usr/bin/install -c

See `config.log' for more details
There is no gcc-4.2 or any other gcc in the /usr/bin directory.
What's up with Xcode?
