Right: what I meant was I hope that the new development won't be  
completely useless on OS X for the same reasons that PART of the  
current development is. See below...

Tried the build. Everything compiled fine, but I got the following  
errors during linking:

Thus it appears that, as I feared, the new modules won't link any  
better than the current ones did. :-( Am I missing something perhaps,  
or is this the problem with OS X linking again?

Thanks for any insight,
