It looks like Snow Leopard broke backwards compatibility with
NSLinkModule as backporting the changes in dln.c from 1.8.7 to 1.8.6
seems to fix the problems for me - at least it lets me load RMagick
without hanging. NSLinkModule and friends have been deprecated for a
while now (10.4, I think) and I'm betting that they didn't get much
attention when Apple were optimising dyld for Snow Leopard.
