compiling on linux ppc

[Carlos Santander]

I'm trying to compile GDC (one of the latest revisions, I'm not sure which one) 
on linux PPC, but I'm getting this:

checking If /home/carlos/dev/gdc-sf/build/gcc/gdc 
-B/home/carlos/dev/gdc-sf/build/gcc/ -B/usr/local/powerpc-unknown-linux-gnu/bin/

(required by /usr/lib/libstdc++.so.6)
no
configure: error: can't compile D sources!
make: *** [configure-target-libphobos] Error 1

I'm using Kubuntu 6.10. The GCC sources are for version 4.0.3. The current GCC 
version is:

gcc version 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)
