Is this any use:

QOF> gfortran46 tmp.f90 
QOF> ./a.out 
/libexec/ld-elf.so.1: /usr/local/lib/gcc45/libgfortran.so.3: version GFORTRAN_1.4 required by /usr/home/mexas/a.out not found

QOF> gfortran46 -Wl,-rpath=/usr/local/lib/gcc46 tmp.f90 
QOF> ./a.out 
z                                                0

This is on FreeBSD, with GCC 4.5 and 4.6 installed from ports.

I believe Axel is right and installing under /usr/lib64
can lead to all sorts of problems.
