Comment (by jhpalmieri):
Two possible ideas, although these could go on new tickets instead: we
could always use `caffeinate` on Mountain Lion, with a patch like this to
the root repository:
{{{
#!diff
diff --git a/spkg/install b/spkg/install
--- a/spkg/install
+++ b/spkg/install

if [ $? -ne 0 ]; then
echo >&2 "Error building Sage."
exit 1
}}}
We could also try to avoid potential issues with gs pointing to gs-X11 by
creating a new link, for example with this possible change to the
matplotlib spkg:
{{{
#!diff

+ ln -s "$GSNOX11" "$SAGE_LOCAL"/bin/gs
+ fi
+fi
+
# Write a configuration file to src/setup.cfg
python make-setup-config.py
}}}
I'm not sure about this second idea, though, because the user might
actually have X11 installed, so we would want a more sophisticated check.
The linbox configure script also calls gs, so we would need a similar
change there.
