well, "make test" has 178 failures, which means... probably all of them, 
not very promising.
So this is FreeBSD, so I wonder what is going wrong.

I configured libobjc2 this way:

cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang 
-DCMAKE_ASM_COMPILER=clang -DCMAKE_ASM_FLAGS=-c

$ make test
Running tests...
Test project /usr/home/multix/code/gnustep-cvs/libobjc2/Build
        Start   1: alias
  1/178 Test   #1: alias 
.............................................***Failed    0.00 sec
        Start   2: alias_optimised
  2/178 Test   #2: alias_optimised 
...................................***Failed    0.00 sec
        Start   3: alias_legacy
<....>

0% tests passed, 178 tests failed out of 178

how can I share you the failure details? where are they?
