One common reason for this error is that your binary has unresolved 
symbols. Try running 'nm' on your binary and make sure that you don't have 
any undefined symbols (i.e look for lines such as
"U _foo").

Steve Majewski posted a patch that makes the error message more 
informative. I recommend downloading dynload_darwin.c and use it to 
replace dynload_next.c.

If you do have undefined symbols, the new dynamic loader won't solve your 
problem. At least you'll be able to figure out what went wrong faster.
