Comment(by jhpalmieri):
A followup: on my mac, perhaps because of various symbolic links, whenever
I run "sage -b", I see a message like
{{{
warning: Replacing library search directory in linker command:
"/Applications/sage_builds/sage-4.6/local/lib" ->
"/Applications/sage/local/lib"
}}}
I can run "sage -b" three times in a row, and I see this message all three
times.
This may be because of symbolic links: "/Applications/sage" is a link
pointing to "/Applications/sage_builds/sage-4.6/".
Perhaps in setup.py, we should use os.path.realpath? For example,
{{{

If this sounds like a good idea, I can open a new ticket with this patch.
