[Click] Compile issues on RHEL 6.4 (2.6.32)

[Keith Schoenefeld]

I should have said "I grabbed the latest tarball from github".  More
specifically, I downloaded the tarball provided at the URI
"https://github.com/kohler/click/tarball/master".  Since the directory
name created when I extracted the tarball (kohler-click-6aa1787)
matches the latest commit, I assumed this matched what I could obtain
using git clone.  Should I install git and run a git clone just to be
sure?
