[R-sig-Geo] rgdal on Mac OS X 10.6.7

[Ralf Schäfer]

Dear list,

I tried to install rgdal in R 2.13.0 on Mac OS X 10.6.7 but it keeps failing no matter if I install from source or binary.

I get the following error message:
Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  kann shared object '/Users/ralfs/Library/R/2.13/library/rgdal/libs/x86_64/rgdal.so' nicht laden:
  dlopen(/Users/ralfs/Library/R/2.13/library/rgdal/libs/x86_64/rgdal.so, 6): Symbol not found: _GetPrivateProfileString
  Referenced from: /usr/lib/libiodbc.2.dylib
  Expected in: flat namespace

System info:
R version 2.13.0 Patched (2011-04-14 r55450)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)

Any idea how to fix this - is obviously somehow related to the iodbc driver or sth...

Thanks in advance
Ralf
