OK.  I was trying to grep for the text--that was a silly idea. :-)

I'm on 10.7, so my path-prefix wrapper points to clang, and since I'm
on Xcode 4.2, ideally there shouldn't be a gcc-4.2 or g++-4.2.

The test gives:

configure:2553: checking whether the C compiler (/sw/bin/gcc-4.2
- -L/sw/lib -L/usr/X11R6/lib) works
configure:2569: /sw/bin/gcc-4.2 -o conftest  -I/sw/include
- -I/usr/X11R6/include -L/sw/lib -L/usr/X11R6/lib conftest.c  1>&5
gcc-4.2: error trying to exec
'/usr/bin/i686-apple-darwin11-gcc-4.2.1': execvp: No such file or
directory
configure: failed program was:

#line 2564 "configure"
#include "confdefs.h"

main(){return(0);}

Looks like ccache-default is the culprit there.  I'd forgotten that I
installed it before updating to Xcode 4.2 .

Now, having removed ccache-default, I get the same failure:

configure:2569: /usr/bin/gcc-4.2 -o conftest  -I/sw/include
- -I/usr/X11R6/include -L/sw/lib -L/usr/X11R6/lib conftest.c  1>&5
gcc-4.2: error trying to exec
'/usr/bin/i686-apple-darwin11-gcc-4.2.1': execvp: No such file or
directory
configure: failed program was:

#line 2564 "configure"
#include "confdefs.h"

main(){return(0);}

It looks like I've got a leftover /usr/bin/gcc-4.2.  My attempt to
install Xcode 4.2 cleanly left this behind.  After moving that out of
the way:

donfigure:2553: checking whether the C compiler
(/sw/var/lib/fink/path-prefix-clang/gcc  -L/sw/lib -L/usr/X11R6/lib) works

int main(){return(0);}

Oops, another leftover stub.

After that, configure seemed normal apart from the following warning:

checking for xcodebuild... /usr/bin/xcodebuild
/sw/src/fink.build/firefox6-6.0.2-2/mozilla-release/configure: line
4577: test: Xcode 4.2 Build version 4D199: integer expression expected

and it's now building.
