gmake[3]: *** No rule to make target `page/SUBSYS.o'. Stop. ??????????????????

Hello,

I downloaded the Postgres-6.5.3.tar.gz, untarred it and followed the configure, make and installation procedures as written in README/INSTALL.

The configure procedure went well, and the beginning of the installation/compilation procedure went also as expected (I have done this once before on Redhat 5.2, with an earlier version of Postgres).

But, at one point the compilation procedure stopped, and ended with a series of error messages like:

gmake[3]: Entering directory `/usr/src/pgsql/postgresql-6.5.3/src/backend/storage/buffer'

gmake[3]: *** No rule to make target `page/SUBSYS.o'. Stop.

etc (there were about 9-10 of these).

and ending with:
gmake: *** [all] Error 2

What does "rule" mean exactly in the message "No rule to make target ......"?

What am I missing on my present installation of Linux?
I suspect it is a missing object file, or a missing header file, but which one(s)?
I have Mandrake Linux 7.0, installed on a Pentium 200 MHz, 64 MB ram.
