[Rd] Problems compiling a simple source package on MacOS X

Hello. I wrote a package (that contains C source) that I've been 
compiling and running on both Linux and Windows for about a year. 
However, that same source package fails to compile on MacOS (10.4.11,  
PowerPC G4, Xcode installed, gcc version 4.0.1, make version 3.80, ld 
version cctools-590.23.2.obj~17).

There is nothing platform-specific in the code-- just numerical 
functions that I wrote in C so they would run faster. It's been a while 
since I hacked Macs... perhaps there is some preliminary step I'm 
overlooking that's so obvious to Mac R developers that nobody even 
bothers to mention it? I would greatly appreciate any suggestions on 
where I should look in order to troubleshoot this problem.

Thank you kindly.

PS: I get the following message when trying to compile either via R CMD 
INSTALL or via the "Packages & Data" menu within the R console:
