generally a blown build just sits there with a build log file so you
can diagnose the problem. Do a regular install, let it blow up, cd
into the gem dir, add your files/patches needed, and finish the build
(make/rake as appropriate, depending on how the gem extension is
packaged up). It builds in the same location it is going to run from,
so you should be good.
