LinuxQuestions.org - An error regarding imlib

I'm running Crux 2.3 and am trying to install IceWM. When I attempted to install IceWM it tells me I need imlib. Great, so I then I attempted to install imlib and I get this error:

Code:

checking gif_lib.h usability... no

checking gif_lib.h presence... no

checking for gif_lib.h... no

configure: error: *** GIF header not found ***

I'm still new to Linux so I looked around and found "libungif" and installed it. This did not fix the problem. Any help?

Thanks,

jer
