Well, all I need is actually C-family languages so I think it'll be ok.
So I've chosen gcc46 port that install 4.6.01 and all seems to work fine.

To use this new version, I had to change some symbolic links in /usr/bin.
Was it right to proceed that way ? By the way, what is the difference between
x86_64-apple-darwin11-gcc-4.6.1 and x86_64-apple-darwin11-gcc-mp-4.6?
What does 'mp' stand for?

Thanks a lot!
