Er, you're right.  I built a "fat" (multi-architecture) Dovecot  
executable on a big-endian PowerPC/MacOSX machine and ran it on a  
little-endian Intel/MacOSX machine.  The configure script does not  
allow for the build and run systems to have different endianness.   
I'll find a way around that.  Thanks!
