That opens the script in textwrangler, which looks like it installs bgrep.
I assume this isn't part of the initial brew installation and I have to
issue 'brew install bgrep'? I'll have to look at the man page and see how
it's used.
Looking ahead:
With macports' different phases, I had to use svn to download reduce. It
has a script that I needed to run after the build phase to change the lisp
library paths. This file is not in the tarball. Does homebrew have a
similar destroot phase? Maybe I won't need that script if the paths aren't
changed. But if I do, does homebrew support svn?

No. I was suggesting you use `brew edit bgrep` to examine the formula for
Bgrep which demonstrates the use of the Homebrew variables `ENV.cc` and
`ENV.cflags` in a system call. This examination should answer
your original question of "What is homebrew's policy on programs that have
explicit 'gcc', 'g++', etc. calls?".
I never suggested actually installing bgrep.

I'm not I understand this system call.
If the configure file for reduce has this line:
if gcc -isysroot /Developer/SDKs/MacOSX10.7.sdk -arch ix86_64 conftest.c
-o conftest > /dev/null 2>&1
how does that system call replace "gcc" with the correct compiler on my mac?

Where is that from? There is no replacement done. Either the Makefile is
edited by Homebrew or the CC environment variable is set so it uses the
correct compiler.

Macports is telling me to patch all config/make files and replace any
explicit "gcc" calls. Which brings me back to my original question: does
homebrew have similar policy?

Okay, so I need to search all the config/make files and replace those
explicit calls. How would this be implemented in a formula?

Either a patch, an inline replacement or an environment variable. These
should all be eventually upstreamed.

If by 'upstreamed' you mean forwarded to the developer, I'm actively
working with the developer on this.

Cool. In that case just tell them they should check and use the CC/CXX
environment variables and set gcc as a default if they are unset.
