Cannot run "mstone config" (on Red Hat Enterprise Linux AS)

Hi All,

We are planning to perform a benchmark test for our mail server,
obviously using mstone. The problem I am facing right now is,
after following the procedures from:

1) http://lxr.mozilla.org/mozilla/source/mstone/Building

2) http://lxr.mozilla.org/mozilla/source/mstone/INSTALL

I was not able to run "mstone config" and the message was:

bash: mstone: command not found

when I checked the "mstone" file permissions, it was:

-rw-r--r--    (for the file /build/package/mstone/mstone)

so I'm guessing that's the reason why. By the way, I'm also a
newbie to Linux so please bear with me.

Then my questions will be:
1) How can I verify that mstone was correctly built?
(I received no errors after building it using "gmake rpackage"
on Red Hat Enterprise Linux AS)

2) How will I be able to run "mstone config"?

Any help or advice is greatly appreciated.

Thanks in advance.
Ariel
