--- Comment #2 from David Chisnall <theraven@FreeBSD.org> ---
The real error is here:

/usr/local/lib/libobjc.so: undefined reference to `_Unwind_SetIP'
/usr/local/lib/libobjc.so: undefined reference to `_Unwind_SetGR'

This is a bit odd, as both of these are inline functions, which wrap
ARM-specific things, in unwind-arm.h in libobjc2:

http://svn.gna.org/viewcvs/*checkout*/gnustep/libs/libobjc2/trunk/unwind-arm.h?revision=37753

I can only imagine getting this if somehow the compiler is not defining __arm__
in the libobjc2 build.
