A binary built on Panther will run on Jaguar. A binary built on Tiger 
will not. I don't know how to get around this currently: the most 
obvious problem is that even a Hello, World binary built on Tiger 
depends on libmx, which is not present on Jaguar. A secondary problem 
is that if your application defines a symbol with the same name as a C 
library symbol (notably for providing functions like dlopen and 
nl_langinfo not present on Jaguar, or making them actually /work/ on 
Panther), the binary built on Tiger still seems to depend on these 
symbols being present in the C library, so it will fail to load with an 
unresolved symbol error on Jaguar. I don't know why this is. For now, 
I'm giving up on Jaguar support for SBCL because of these issues; you 
may also find them an issue with OpenMCL.
