New issue 618: Install script fails when compiling with gcc provided by MESA sdk https://bitbucket.org/yt_analysis/yt/issue/618/install-script-fails-when-com... Nathan Goldbaum: It seems a lot of people have the gcc provided by the [MESA](http://mesa.sourceforge.net/) sdk in their `$PATH`. The install script currently fails while trying to compile mysql using this compiler. I've only seen this on a mac, and while building yt with xcode's gcc still works, it's a bit confusing for new users who aren't familiar with POSIX semantics. Fixing this will require testing with a MESA install on a mac. Hopefully there's some way to determine that we're using the MESA sdk compilers so we can either warn users or adjust the defaults automagically.
