PM3 and an Alpha

["Bill Anderson" <rescatex dmv com>]

I'm trying to get my shiny new PM3 to work with my shiny new 164SX running
RH5.1, 2.0.30.
OK, I run setup, which goes into /usr/portmaster.  Then I'm supposed to
configure it with pminstall. Seems straightforward
No matter what I've tried I keep getting

     alpha_2.0 program directory not found in .

What am I missing here?  Anybody have an ideas for a clueless Alpha newbie?
Any help would be greatly apprecitated!

Thanks,
Bill
