this shows that your [R <-> Mac OS X]  setup is broken,
at least for *building* things like the one above.

Note that this is *NOT* a bug in R, and sending it to R-bugs was
not appropriate. Sending to 'R-devel' would have been
appropriate,
but really it is recommened to use the Mac specific mailing list,
R-SIG-Mac  (--> http://stat.ethz.ch/mailman/listinfo/r-sig-mac/
for problems like yours.

    ak> Can you help me ? 

Not more than that, 
but I am sure some of the reader of R-SIG-Mac  can help you.
