William Kyngesburye provides many UNIX frameworks as OS X binaries on his web 
site:

As of this writing he still has rgdal for R 2.5. He also has advice for 
compiling under OS X.

It appears to be an architecture mismatch. Did you upgrade from 10.4.x to 
10.5.1 but not upgrade XTools? My MacBookPro with 10.5.1 and XTools 3 has 
/Developer/SDKs/MacOSX10.5.sdk as well as the older 10.4u.
