Have you tried removing one of the prefixing underscores? It could be
that the prefixing rules have changed, though I haven't heard anything
to that effect..

Does dlsym(...) not work the same on Intel Macs? I have some symbol
loading code that works just fine on PowerPC Macs, but on Intel
Macs, it returns NULL. Here is a line.
int *debug_addr = (int *)dlsym(mainHandle, "__debug_level");
This loads the symbol named `__debug_level'. This code is executed
from a dynamically-loaded bundle, and it loads the address of the
symbol from the main executable. On PowerPC, I get the address you'd
get by doing `nm' on the executable. On Intel Macs, I get NULL. Any
ideas what's happening here?
