Wow, that is really unexpected. Also weird, because I tested the entire
library overnight on my local 4.8.alpha4 (for another ticket) and nothing
happened like that, or I would have noticed this morning.
{{{
new-host-2:sage-4.8.alpha4 karl-dietercrisman$ ./sage -t
devel/sage/sage/interfaces/r.py
sage -t "devel/sage/sage/interfaces/r.py"

All tests passed!

Of course, I also get
{{{
> capabilities("png")
png
FALSE
}}}
Your problem is that someone Sage got compiled with png support! It's not
supposed to on Mac, we try to configure it to use (only) Aqua. Hence the
doctest being a little unusual:
{{{
sage: s = r.eval('capabilities("png")') # Should be on Linux
and Solaris
sage: t = r.eval('capabilities("aqua")') # Should be on all
supported Mac versions
sage: "TRUE" in s+t # optional --
rgraphics
True
}}}
My guess is you have something set in your preferences or elsewhere that
caused R to pick up a system version of something. In general, getting R
to compile on Mac with png support is interesting and hackish - I can't
find the page I'm looking for right now, but it's referenced somewhere on
one of the previous "get graphics in R in Sage to work" Trac tickets.
In other words, while not ideal, I wouldn't call this something to unmerge
this new spkg for.
