f95 portability (newbie question)

I just started using sun's f95 on my laptop (Pentium M, Ubuntu 7.04) and it has been working fine...but, with the goal to take my executable and run it in a larger computer, 4xOpteron275 running:

Linux ***name 2.6.9-42.0.10.ELsmp #1 SMP Fri Feb 16 17:13:42 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

I compiled at home with:

f95 xyz.f90 -xtarget=opteron -m32 -O5 -libmil -openmp

But when I "ftp" the a.out and run it in the larger machine, I get:

"error while loading shared libraries: libfsu.so.1: cannot open shared object file: No such file or directory"

Am I missing something?
