[R-SIG-Mac] Rmap package and Darwin/X11 R

[David Firth]

Has anyone got Barry Rowlingson's "Rmap" package (see
    http://www.maths.lancs.ac.uk/Software/Rmap/
) working on OS X?

I have tried and failed.  I reckon I didn't do the right things with 
the proj4 and shapelib libraries, to build them as shared libraries 
("dylibs"??).  Can someone give me hints on how to do that, and whether 
I need to do anything OSX-specific to the Makevars in file in Rmap/Src 
(eg to tell it to look for blah.dylib rather than blah.so?  is that 
necessary?)

All the best,
David
