[OctDev] How to make configure recognize libpng, libjpeg, gsl and qhull ?

[R S A. M. <rsa...@sa...>]

Hello:

I am trying to compile octave-forge-2004.11.16 on a Slackware 10.1
system. I have installed cln, ginac, libpng, libjpeg, gsl, qhull. When I 
run ./configure it recognizes only ginac.

Can anybody help? Thanks for your help.
