Not really, it is a fundamental problem with Rlibstemmer.

First, cc and gcc are the same thing in Xcode so that's a red herring. Second, setting CFLAGS/CCFLAGS has no effect on the package itself, those are ignored and it uses R's settings. [Note that the flags you specified are nowhere seen in the listing you sent]. Third, the way Rlibstemmer is build is fundamentally broken, since sources are actually outside of the src tree so they will be wrong - and you can see that from the output "make: Nothing to be done for `all'." indicates that nothing is actually built for the architecture since R has no way of knowing about them.

[... I was trying to fix the sources to demonstrate wheat needs to be changed, but it was more than I hoped, so I gave up and never sent this ...]

I may try to give 0.1-0 a shot, maybe it's easier to fix than 0.1-1 ... 

Cheers,
Simon
