Calling 32 bit libraries on an x86_64 in 64 bit mode

I have a set of proprietary libraries that are i386 compiled code under
Linux. They are called from a perl module.

This worked fine until we moved to a dual AMD64 system. Now it is choking
in DynamicLoader.pm.

Is there a clean way to call a 32 bit shared library from a 64 bit version
of Perl? Is there some sort of option to get XS to emulate a 32 bit mode
or is it just bjorken?

No, there isn't. Leastways, this is a restriction on Solaris. You have
to compile the libraries in 64-bit mode or build perl as a 32-bit
application to get compatibility.

Mixing the modes probably won't work.
