Can't build in Lion, because gcc-4.0 is gone after xcode 4 killed xcode 3

[GoogleCodeExporter]

So, on my Lion 10.7.2, and apparently on all Lions, gcc-4.0 is forever gone. 
:-( And thus, pygr can't compile.

So I've spent some time looking it up. And with "some time", I mean several 
hours. 
http://hints.macworld.com/article.php?story=20110318050811544
http://useyourloaf.com/blog/2011/7/20/hello-lion-goodbye-xcode-3.html

Etc. Hundreds of Mac users, complaining that gcc 4.0 apparently doesn't work in 
Lion anymore. Lion doesn't allow xcode 3.0.

Am I really the first Lion user to try to build pygr, and notice this? Or is 
there a way around this death crippling.

Hi, thanks for the report. Could you please make sure that your build directory 
is empty and try again? The fact Python quite clearly states in your output it 
thinks it's building Pygr on MacOS 10.3 is... suspicious.

I can't disagree with that. 
I emptied the build folder, and ran it again:

No 10.3 this time,  and now build folder is empty.

Also, when I just try to execute the setup.py, I get the same error, again with 
the 10.3's:
