Staden Package

Hi all,

I've downloaded staden-1-6-0 and i am working on a red-hat system

I've closely followed all the installation instructions but I run in to the
following problem,

On the license request site they mention ".... .Once the package is
correctly installed, run the program gap4 and it will display a window which
contains a string of symbols, unique to your installation, termed the "Host
ID" "

But, when I try to run gap4 the ffg occurs

"""
[root@...]# ./gap4 &
[7] 6435
[root@... ]# ./gap4: line 123: exec: stash: not found

"""

What could be the problem here?

Thanks,

Hamilton
