R does not work inside sage if LD_LIBRARY_PATH includes /sw/lib.
(Which it ordinarily wouldn't, that was a mistake of mine.) That bug
is pretty trivial and easily fixed.
But I found that R is the only component of sage that links to system
frameworks. (Aside from python.) That seems to be a bit inconsistent
for sage, i.e. R obviously does not link to Apple frameworks on other
platforms.
The aqua device is compiled in Mac-sage-R, though my feeling is that
it wouldn't be a drama to remove it. There is plenty inside the R
configure script about detecting CoreFoundation, though no simple
option. I think it would be a good idea to switch off CF as well as
Aqua.
So the two questions are:
* would switching off Aqua have any benefit, or inconvenience anyone?
* would switching off CF be a good idea too?

=== BACKGROUND ===
r.eval('1+1') fails
The fail message includes the following:
before (last 100 chars): ions/A/Frameworks/ImageIO.framework/Versions/
A/ImageIO
Expected in: /sw/lib/libJPEG.dylib
sage -t r.devel/sage-main/sage/interfaces/py fails, or fails to complete
sage -testall only gave problems with R, suggesting the fault lies
there.
=== FIXES ===
All of these work:
* Renaming /sw so that the offending library can't be found.
* Removing /sw/lib from LD_LIBRARY_PATH
* Setting OSXFW="--enable-R-framework=no --with-aqua=no" inside R spkg-
install
