[Rd] How to get R to compile with PNG support

[Karl-Dieter Crisman]

Followup with the specific issue in our most recent (non-posted, as of
yet) attempts on a certain box.  We now have xorg-dev, libcairo-dev,
and Xwindows.h and libpng (as below) on this machine, but R is not
compiling with support for any of these things.

Once again, any help knowing *exactly* what to pass to the
configuration script or anything else would be *greatly* appreciated.
We are planning to use R in Sage on several occasions with this
machine this summer if we can get this going (see
http://www.maa.org/prep/2011/sage.html).
