Hello Brent, Please send the code, i'll look at it asap.
I am precisely in a discussion with developers about goops and the way the guile module system interferes with it, since i also believe that there is a serious problem indeed: and not 'just' because there is no way to ask goops 'stuff' to land in a single module, but because if you don't do the right [counter intuitive] thing then export actually exports single class capable accessors and methods instead of the generic. Anyway, please send your code, because there is a way to make it run, it's just a matter of you understanding how and i'll do my best to help you.
