I have a closed-source 32bit database application running on a 64bit CentOS 5.2 system which is running very well however i am looking at developing some python applications that require access to the data and the vendor only provides a 32bit c library.
So while attempting to utilize the library in python with ctypes it became obvious that the 64bit python cannot use the 32bit c library.
So what are my choices?
Yum and so many of the applets (system-config-*) are tied to Python that you can't mess with the base version or arch of Python.
What about a 32 bit chroot using Mock? I've never done it, but that's what Mock is intended to do.
Perl.i386 will run OK in x86_64 and there is a version of perl-Inline-CPP that will allow you to write most of what you want in CPP and wrap it with Perl.

I am afraid we are stuck with Python. A considerable amount of the work has already been done but it has been developed on a 32bit system and it wasn't until early testing revealed our 64bit issue. One of the primary objectives is to develop a SOAP interface to the application and that has also been started using TurboGears.
The vendor has offered to port the library to 64bit for a 5 figure amount.
