Sorry about that.  I had forgotten that I put a lone spec file in there.
I have removed it, since it seems likely that I will do the same thing
in the future.

The perl hack used to be required because rpmbuild installs R in a build
root which is different from the final installation directory. The
reason you don't see an error message from the post install script is
because it is redirected to /dev/null. I'll fix this in the next
version.
