[Rd] 2.3 issues on Mac (PR#8915)

[ryan at stat.Berkeley.EDU]

/Library/Frameworks/R.framework/Versions/2.3/Resources/etc/ppc/Renviron and
/Library/Frameworks/R.framework/Versions/2.3/Resources/etc/i386/Renviron
both use /usr/local/teTeX/bin/powerpc-apple-darwin-current for LaTeX
related variables. Could this be updated for i386 to take into account the
teTeX intel binaries?

Also, Makeconf is not setup to create universal binary libraries. Will this
be done at some point?

Lastly, R.mpkg crashes Apple's Remote Desktop 2.2 when installing on a
client. I was wondering if anyone else sees this?

Thanks,
Ryan
