I'm afraid that the instractions there could be outdated. Downloaded file
(djcross-gcc-4.6.2.tar.bz2) contains SPEC file which should be used. I also
used specified versions of several external packages. The simplest is 
perhaps
to download SRPM from either my homepage or from ftp.delorie.com
(from pub/djgpp/rpms).

Binary RPMS there are built under CentOS-5.7 (or 5.6) 32-bit and are 
statically
linked with several libraries (like GMP, MPFR, MPC) to avoid unnecessary 
dependencies
and are working also for example under Fedora 16. Building from my SRPM is
also verified to work under Fedora 16 x86_64.

I do not remember seen similar problems with my SRPM packages. I have 
not however tested on opensuse
