building gdc on Debian 64-bit (wheezy)

[Brad]

Does anyone know how to get gdc to build on a 64-bit linux machine?
I can build gdc on linuxmint11 (32-bit) and gdc v2 on FreeBSD 8.2 (32-bit).
I have included below the script I use.
I've tried removing "." from PATH; I've tried --enable-multilib and --disable-multilib.

The error I get is:
