[Click] Compile issues on RHEL 6.4 (2.6.32)

[Eddie Kohler]

Hi Keith,

I got a look at this. There were a couple problems with that kernel
that our rewriting, etc. tools could not handle. I were able to fix
them and get a pretty clean automatic compilation. These patches are
committed. However, an installation attempt fails with "out of
memory". I haven't debugged further. Have you gotten further?

BTW, I didn't realize you were downloading the current tarball from
github. You did get the latest commit, but I'd strongly advise you to
install git, which will make it easier to update.
Eddie
