[Nagiosplug-help] Make file returns an error

[melvin.a.farber at census.gov]

When trying to make the nagios plugins I get the following output and error
after running make all.

No suffix list.
Making all in lib
Making all in plugins
Make: Must be a separator on rules line 959.  Stop.
*** Error exit code 1

The Makefile in directory plugins only has 938 lines.

I would appreciate any ideas or help.
I am running the make on HP-UX 11.11.

Thanks,
Mel
