I installed base, gui and back from svn.

here the test results from gui, compiled with gcc 4.2.1 and the gcc libobjc:

773 Passed tests
  5 Failed tests

setting the breakpoint on -[NSException raise] did not stopped anywhere.

It was hanging when testing NSObject initialize, so I killed it on another 
shell, to get into gdb, this is what the backtrace looks like first it hits an 
exception:
