[R-SIG-Mac] problems with X11 in R 2.11.0

[Prof Brian Ripley]

Something is wrong with your system software.  On my Leopard box:

tystie% otool -L 
/Library/Frameworks/R.framework/Resources/modules/i386/R_X11.so
...
 	/usr/X11/lib/libpng12.0.dylib (compatibility version 42.0.0, 
current version 42.0.0)

So your /usr/X11/lib/libpng12.0.dylib is different from mine (and from 
the CRAN build machine's).

Your choices are

- to resolve this (and it is not an R issue). I'd start by running the 
software updater ....

- to build R from the sources against the software on your machine.
