Is there a workaround to this bug?  Issue #87 talks about it but it
looks like no one is responding to comments...  Anyway, I've tried all
kinds of symlinks, parameters, and environment variables and yet its
seems to pull the path /Volumes/Macintosh HD/ no mater what I do...
I've tried manually installing via ./configure, make, make install
still not love, even editing the build file by hand...  any ideas?
Here's the error I get on bundle install:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native
extension.

Out if ideas... anyone else have an idea on how to get past this?
