Oh, you're already linking by the framework method? Otherwise I'd have 
expected a dependancy on libkrb5 itself and not on the framework.

This is probably one of those messy cases where you need help from the 
invoking application, but I'd have to write a test program to prove it to 
myself.

One thing you can try if you get stuck, is to link archive libraries into 
the pam_krb5.so object and see if they're either archives of PIC code, or 
if the linker will do relocations of non-PIC code to PIC and thus not need 
the shared libraries at all.
