-        Gambit will build with GCC if an acceptable version is found on your
-        system, or Clang otherwise.  If it finds only Clang, the build will
-        take a very, very long time.  Programs built with Gambit after the
-        install may also tke a long time to compile.

-        You can remedy this by installing an apple-gcc* or gcc* package.
+        Gambit will build with Clang, however the build may take longer and
+        produce substandard binaries. If you have GCC, you can get a faster
+        build and faster execution with:
+          brew install gambit-scheme --cc=gcc-4.2 # or 4.7, 4.8, etc.
