Ouch, this makes it almost a dead end for us. I can offer some time to  
help in this effort, working in the port, or providing feedback. The  
native dynlink and toplevel are, at least to me, the killer features  
in 3.11, but adding another hole for Mac OS X intel (in addition to  
not supporting x86_64) does not seem like the best choice for an  
increasingly popular architecture.

Again, thanks for the good work!
