Always works here :)

[wallstreet:xufs/gcc-cvs-clean/objdir] andreast% ./gcc/xgcc -v
Using built-in specs.
Configured with: /Volumes/xufs/gcc-cvs-clean/gcc/configure 
--prefix=/Volumes/xufs/gcc-cvs-clean/testbin 
--enable-languages=c,c++,java --disable-checking --enable-debug
Thread model: posix
gcc version 3.5.0 20040220 (experimental)
(it doesn't matter if 3.4 or 3.5 both work the same way).

You may have to take the absolute path for the confiugre.
