There is one earlier SRPM

ftp://ftp.delorie.com/pub/djgpp/rpms/djcrx-2.04pre-5.src.rpm

which does not depend on existing cross-compiler build. It uses prepackaged djcrx204.zip package. 
Later versions uses CVS snapshots of DJGPP library sources.

It is old and current rpmbuild complains about target related packages present in noarch package. 
You can change target to x86_64 in SPEC file. After that RPM package builds OK in Fedora 16 x86_64.
I have not tried CentOS-6.2. My available builds for ix86 are done in CentOS-5.X chroot under 
Fedora x86_64 version.

djcrx RPM contains stubify and stubedit executables, so it is target dependent.

One can install 32 bit packages in x86_64 linux installation, but not in opposite direction. As 
result only 32 bit packages were provided . You do not need very much for my RPM builds of 
cross-compiler. Of course that assumes available root access on system.
