GDC on 64 bit linux fails (gentoo)

[Anders Johnsen]

I'm trying to compile GDC 0.22 in 64 bit with GCC 4.1.1. I followed the guide but recived this error.

If you meant to cross compile, use `--host'.
See `config.log' for more details.

Anyone have same error, or just successfully compiled in 64 bit linux? Also, are there any plans on making some binary releases of GDC or DMD in 64 bit? 

Thanks,
