Yeah, that's my problem, too :-)

The ld man page says

   Options when creating a bundle
     -bundle_loader executable
             This specifies the executable that will be loading the bundle
             output file being linked.  Undefined symbols from the 
bundle are
             checked against the specified executable like it was one 
of the
             dynamic libraries the bundle was linked with.

That doesn't look like the right thing.
