this should not happen. Now we only change this in the installed 
version of R not in build dir. Do you have another R in the path 
breaking up things?

what we do now is:
* nothing in build dir of R, because of the problem above.
* we changed etc/Makeconf in the R.framework only after R.framework 
installation
could you please try to see what yo have in etc/Makeconf and bin/SHLIB 
inside your build dir? I mean, did you happen to have -framework R 
somewhere? ($LIBR)

ehm and surely you have done the build on a fresh (and cleaned) 
rysinced version of R-devel :)

so, it doesn't work at all. This means that, that patch should not be 
applied on Jaguar and further means that I have to identify which 
version of OSX is running.

thanks Simon,
