[R-SIG-Mac] question about installing from source

[Mark Daniel Ward]

I am trying to install the Rcartogram library.  I've never had trouble doing 
this before, but I recently upgraded to Snow Leopard, which may be causing a 
problem.  I do have FFTW3 installed on my machine, and I've never had trouble 
with it before either.  I even tried installing FFTW3 again, but this did not 
seem to fix the problem.

Here is the error I get when trying to install the Rcartogram library from 
Omegahat.  If anyone has any suggestions, I would really appreciate it.
