This doesn't sound right -- I don't think we changed how linking worked in 1.6.3 and 1.6.4.
Are you sure that, on that same machine with MPICH installed in /usr/lib64, you're also able to compile/link/use 1.6.3 properly?
A wild guess: you have some kind of linker configuration that is putting /usr/lib64 ahead of -L-specified paths on the compiler command line.
