[Slackbuilds-users] ocropus compilation error

[Nikos Skalkotos]

I tried to compile ocropus and I get errors like those below.
ocropus states iulib as it's dependency. It looks like iulib needs an SDL
library, maybe SDL_image, but iulib's README file does not state anything
about this and I can't find an SlackBuild script for it. Any Hints? Am I
doing something wrong?

P.S. I'm using slackware-current and the slackbuilds I used are from
slackbuilds.org 13.1 repository.
