FLUKA error in Ubuntu

Good day everyone, I am getting an error message when trying to run
FLUKA in Ubuntu 8.04 and was hoping for some assistance.

To compile and link, I use terminal to go to my fluka directory after
copying the modified source.f file.
$FLUPRO/flutil/fff usermvax/source.f
$FLUPRO/flutil/lfluka -o myslab -m fluka $FLUPRO/usermvax/source.o

Then in my geometry directory, I type:
$FLUPRO/flutil/rfluka -e $FLUPRO/myslab -N0 -M1 slab

This outputs to the terminal:

$TARGET_MACHINE = Linux
$FLUPRO = /home/ariel/myfluarea
/home/ariel/myfluarea/libec_thihecufealw_10t.pemf
7329: old priority 0, new priority 10

I have had problems before with Ubuntu being "too" user-friendly, am I
just missing some package that lets terminal interpret the -e
command? The user next to me is running on OpenSUSE 10.3, and using
the exact same procedure, the script runs fine. Thanks,
