"Mach-O Runtime Architecture" from Apple, it's in the developer 
documentation that gets installed with the tools.
"man 3 dyld" is part of that in manpage form, but only part of it.

Hmm, I was really hoping g++ would be the answer. What you could also 
try for debugging is turning on the various environment variables 
mentioned in "man 1 dyld", they might make clear when exactly your 
import is hanging.
