[R-SIG-Mac] package compilation problems

[Prof Brian Ripley]

Something has put /usr/local/lib/libiconv.2.dylib on your system, and 
it is not universal.  You should not need it: there is a system copy 
in /usr/lib.

You are going to need to investigate this for yourself -- it is not an 
R issue and I've no idea what might have put libiconv there.

Also note the R CMD INSTALL option

       --no-multiarch	build only the main architecture

which would have worked around this.
