[R-sig-Geo] compiling spproj on osx

[Horacio Samaniego]

I got to the point where I would need the spproj package to reproject  
som sp dataframes. However, when I try to install the package from  
http://r-spatial.sourceforge.net/R/src/contrib/spproj_0.3-4.tar.gz,   
I get the following error.
Is this an incompatibility with os x 10.4 or am I missing something  
in my path?
