While cc and gcc are perfectly in their right path (/Developer/usr/bin in OS X Lion), running ./configure tries to compile it

    Item 1 correct: I just did the same thing.

    Install XCODE Launch XCODE Click on Xcode Choose Preferences Click on Downloads in the XCode Preference pane Click on command line tools and click "Install"

    The compilers are install in /usr/bin

    cd there, and type "gcc -v" (without the quotes)and you should get back the following:

    $ gcc -v
    Using built-in specs.
