Compile error: command not found

Hi all!

I downloaded 8.3.1 and ./configure and gmake went smoothly during the
installation process. But when I ran gmake install, I had these
errors:

**********
gmake[3]: Entering directory `/root/postgresql-8.3.1/src/backend/utils'

gmake[1]: *** [install] Error 2

and gmake stopped. Any ideas as to what I can do to fix this?

I'm running a recently installed Slackware Linux 12.0 on a linux-only box.
