Re: Unable to install ROOT version 5-32-01 on mac 10.7.3 with gcc version 4.2.1

Did you install the latest Xcode 4.3 on you machine? If so you need to install, seperately, the command line tools, like compiler etc. In Xcode 4.3 go to Preferences/Downloads and make sure that "Command Line Tools" are downloaded. That will give you the official clang++ compiler.

Cheers, Fons.
