Subject: [PATCH] os/mac/xcode: fix CVS/GCC check if no Xcode
On systems prior to 10.9, formulae that use CVS as a download source
check whether the installed Xcode already provides CVS to avoid adding
a dependency on the `cvs` formula. Unfortunately, if no Xcode is
installed the check fails with
undefined method `<' for nil:NilClass
causing the formula to become unloadable. This in turn causes some taps
to be untappable since #396 added the `readall` check on `tap`.
Closes #508.
