Comment:

 Thanks. It'll take me awhile to build the dependencies on my second
 machine; ghc does not build on my primary machine (#42091).

 We should keep the patch to tell pure-gen where to find gcc. In your
 Makefile you now do this on Darwin:

 {{{
 gcc = $(lastword gcc $(sort $(wildcard /opt/local/bin/gcc-mp-*)))
 }}}

 However, this assumes the MacPorts prefix is /opt/local (it could be
 elsewhere), and it assumes the user would like to use the most recent
 installed gcc. Instead, we want to use the specific gcc which the user has
 requested via the corresponding gcc''NN'' variant.

 This Makefile line will also not be helpful for users of manually-
 installed gcc, nor those using package managers other than MacPorts (there
 are two other popular OS X package management systems).
