R devel - Feb 2004 - Math Symbols in plots under Darwin/Panther

I've just committed a new version of the quartz device to R-devel.
This seems to fix the problem with displaying math symbols in plots 
under Panther.

I can't not more test R under Jaguar (at least not these days). In case 
you have the opportunity to do that, please send me a report if it 
brokes everything under Jaguar (or eventually say "it's ok")
A couple of test as example(plotmath) and demo(plotmath) should suffice 
to see if things go smoothly.

I gave it a shot on a Jag machine (darwin 6.8), here are my results.

Do we have the chicken-and-egg problem again?
during the build, while building R_X11.so:
ld: can't locate framework for: -framework R

I thought this was fixed a while ago: you can't use -framework R when 
building R modules, because R is not installed as a framework yet. I 
had proposed the fake framework for building or different flags for 
initial build and packages build, but I don't remember which solution 
was used in the end - and it seems like none is used in the current 
R-devel :P

The quick-and-dirty way to bypass the above is something like this:
sudo bash
# this will fail, but at least create the proper directories
make install
# we need to copy at least the library
mkdir /Library/Frameworks/Versions/1.9.0/Resources/bin
cp bin/libR.dylib /Library/Frameworks/Versions/1.9.0/Resources/bin
cd /Library/Frameworks/R.framework/Versions
ln -s 1.9.0 Current
cd ..
ln -s Versions/Current/Resources/bin/libR.dylib R

now you should be able to re-run make
this is just a hack for those who get stuck and want to test the 
R-devel anyway. Fixes for this problem are those discussed before.
(I was away for a week so I didn't test R-devel in the meantime and I 
strongly suspect that this is not Jag-dependent)

Well, define "smoothly" - on the Jag machine I tested the font face is
constant and all math symbols and operators appear as boxes - i.e. the 
font is not changed, but no errors or crashes.
