Yup, it's part of the same thing.  Currently, libobjc in the base system is the 
only thing that doesn't compile with clang (because clang doesn't implement an 
option specifically designed to give information about the ABI to libobjc, for 
use in a code path that no one sane actually uses, and I can't be bothered to 
implement such a pointless feature).  

The other problem is that, even if it did, the libobjc in the base system has 
the old runtime exemption which only applies to code compiled with GCC, and if 
Clang is the system compiler then this is far from ideal because it means all 
ObjC code compiled with Clang would be GPLv2.  

The simplest way around this for the FreeBSD folks is to strip libobjc from the 
base system, move it into ports, and then you can install GCC libobjc if you 
install GCC, or libobjc2 if you don't.
