[plt-scheme] Dynamic loading of multiple mzscheme modules on hpux built with SWIG

I have build a collection of modules for mzscheme (209) using SWIG:

Version 1.3.24
Compiled with aCC [hppa2.0w-hp-hpux11.00]

I am using "mzc" (using  the HP aCC compiler) to build and link them.

I am fine loading up my first module:

   (require (lib "module1.ss" "ccl"))

But when I go to require my second module:

   (require (lib "module2.ss" "ccl"))

I end up with the following error in Scheme:

   require: unknown module: |,/usr/local/plt/collects/ccl/module2|

I have isolated this fault down to module2's scheme_initialize()
attempting to call its own scheme_reload(), but picking up the
scheme_reload() in module1.

How do I build shared libraries which call their own functions
themselves. Remember that I am limited by:

1. the modules are auto-generated by swig, and therefore I can't
    delegate the scheme_reload functionality to a static function

2. mzscheme contracts me to use those names, by its "module" API.

3. as much as I may love gcc, I am stuck with acc/aCC so I *really*
    need compiler/linker flags for those.

Thanks very much in advance for you help.
