> 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.
Of course. `distutils` reads the Python Makefile each time it is invoked
by the Sage library's `setup()`; we do not (yet) patch that Makefile and
`pyconfig,h`.
> This may be because of symbolic links: "/Applications/sage" is a link
pointing to "/Applications/sage_builds/sage-4.6/".
Yep.
> Perhaps in setup.py, we should use os.path.realpath?
> If this sounds like a good idea, I can open a new ticket with this
patch.
Well, it's just a warning; feel free to open a ticket for that, and I'll
probably review it. ;-)
