Comment:
Doctests pass on bsd.math (Mac OS X 10.6) with the option:
{{{
[mv...@bsd sage-4.4.1.rc0]$ ./sage -t -long devel/sage-
main/sage/interfaces/r.py
}}}
But doctests would fail with:
{{{
sage -t -long --only_optional=rgraphics "devel/sage-
main/sage/interfaces/r.py"

The following tests failed:
sage -t -long --only_optional=rgraphics "devel/sage-
main/sage/interfaces/r.py"
Total time for all tests: 3.0 seconds
}}}
Making the specified doctests optional mean we're postponing a fix for the
failure for a later time. Note that the above doctest failure is specific
to Mac OS X as far as I can tell.
