Lost my path after upgrading to Lion GM? How do I fix this?

Question

I just upgraded to the GM version of Lion. I've been using the previews without a problem, but something happened with the latest install and I lost my "path", so now I can't compile anything with gcc or g++. I finally found gcc and g++ in /Developer/usr/bin, but now it can't find the include directories.

Is there a simple way to fix all my paths so my tools will work again? Or is reinstalling Xcode the easiest way to fix that?

I say "path" because I don't know all the different places path information is stored on OS X.

Answer 1

Reinstalling xcode fixed everything.
