Cannot compile on Slackware 10.2

Hi list,

I downloaded Postgresql 8.0.4, and tried to compile on Slackware 10.2.
However, the configure runs fine, but when I run 'make' (or 'gmake') after
that, it executes the configure again (and again, and again.......), without
actually making the application.

Any ideas?

Cheers,
D.Kniep
