That's not a problem -- the build script builds 2 versions of some 
files, and the first time through they don't exist, so you get that 
error, which is ignored.

The problem is with the Freetype library, which is being detected at 
build time but which is not available at run time.  All I can say is 
that it works for me, I don't know why it doesn't work for you.  (I'm on 
OS X 10.4.11, you're probably on 10.5?)  You can try to configure rgl 
without Freetype by using --disable-ftgl as a configure option, i.e.

R CMD INSTALL --configure-args=--disable-ftgl ...

but I don't know how to get it to work.

I've copied this to R-sig-mac; maybe someone there can suggest a fix.
