gmake4.1 not found

[amante at grouse.pnl.gov]

I just downloaded the upd_pkg.1.cpio from the server, upacked it (following
the README instructions enclosed) and then couldn't get past the 
sh update.sh because there was no gmake4.1 file in the package.  Can anyone
tell me how to get around this problem???  Specifically, where is gmake4.1
or do I have to unpack the unpacked upd_pkg.1.cpio package more???

Please respond to amante at grouse.pnl.gov
