compiling arts

Hi everyone,

I'm trying to compile arts on my machine following Wiki instructions. I
applied mac-arts.patch and ran configure-kde from the patch. Now when I
'make all' I get the following error:

g++-3.3: unrecognized option `-pthreads'
/usr/include/gcc/darwin/3.3/c++/ppc-darwin/bits/atomicity.h: In member
function 
   `void Arts::TraderCheck::run()':
/usr/include/gcc/darwin/3.3/c++/ppc-darwin/bits/atomicity.h:65: error: `asm'
   operand requires impossible reload
make[2]: *** [tradercheck.o] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

The g++3.3 error comes up a number of times during make, actually.

Is it the option '-pthreads' causing the trouble? How do I turn it off?

Thanks!
Alexey
