Compiling on an alpha

[Mike Sullivan]

I am trying to compile the 1.03a and get when I run configure

Configuring for a alphapca56-unknown-linux-gnu host.
Invalid configuration `alphapca56-unknown-linux-gnu': machine
`alphapca56-unknown' not recognized
Invalid configuration `alphapca56-unknown-linux-gnu': machine
`alphapca56-unknown' not recognized
Unrecognized host system name alphapca56-unknown-linux-gnu.


what is the correct host, I have an 21164PC based SX MB running redhat
5.1
