[R-SIG-Mac] Difficulty compiling packages with c code with R-2.4.0

[Strand, Allan Edgar]

Hi All
    I am working on a powerPC (G4) mac with OSX version 10.4.7.
    I upgraded from r-2.3.1 to r-2.4.0 recently using the universal  
    binary dmg file downloaded from CRAN. This is the complete, not mini  
    binary.

    The interactive environment works great, but I am having difficulty  
    installing packages that require C/C++ code to be compiled. This  
    includes my own packages and I have also tried the Matrix package.
    It looks like compilation is not the problem, linking is.  In  
    particular, when linking object files, every package install dies  
    with this message:
 
   /usr/bin/libtool: unknown option character `m' in: -macosx_version_min

    I use fink and libtool is installed at version  1.5.10.  Clearly this  
    looks like a configuration problem with my machine, but I am a bit  
    confused on where to go next.  Any pointers would be greatly  
    appreciated.
    cheers,
