Thank you to everyone who helped me on this one....

The trouble *was* the Cobol call to dlopen() ... it did _not_ have the 
RTLD_GLOBAL flag set on their load of my extention (their own way of 
extending). (After some quaralling over dlopen() i finally got them to 
send me a patched version of their runtime with RTLD_GLOBAL to test).

Conclusion: in the *first* call to a chain of dynamic objects, it is 
neccesary to do dlopen() with RTLD_GLOBAL - otherwise python will not be 
able to export its symbols to its own symbols.
