Well, that's just stupid!  One of two things need to happen:
- distutils and scipy_distutils need to be fixed to be able to mangle 
environment variables before invoking the toolchain
- distutils and scipy_distutils need to do something reasonable 
instead, like replace the $(CC) variable before substitution, not the 
first word it sees after substitution.

This may be an issue for 10.4 though, as the public sources in the WWDC 
build were a slightly modified 2.3.3 that used this style LDSHARED.  I 
guess the solution in this case is to backport both patches back to 
2.3.4 and get a 2.3.5 release cut, which Apple would hopefully pick up 
if enough bug reports are filed and emails sent :)
