R devel - Mar 2010 - 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:

* installing to library '/Users/barshop_lab/Library/R/2.10/library'
* installing *source* package 'Survomatic' ...

You don't have the necessary tools -- your compiler+linker is too  
ancient (so is your OS, but that's another story). Please install  
Xcode 2.4 or higher --  see R for Mac FAQ and/or visit
http://R.research.att.com/tools/

In addition, please consider looking at R-SIG-Mac where Mac-related  
discussion takes place and this has been discussed before (stuffing  
the error in google gives exactly the relevant hit on the list...)

Cheers,
Simon
