only GIF textures are read

Thanks in advance for your time. My versions are:
CrystalSpace 1.0.1
Ubuntu 7.04
GCC
ATI Technologies, Inc. Radeon Xpress 200M (RS482)
fglrx

I installed a new version of Crystal Space on my new laptop and code which was previously working now has a strange problem. When I run my program, things are fine except that only textures that are GIF images will load. Everything else gives errors to the effect of

Code:

crystalspace.maploader.parse.image:
Could not load image 'P1013493.jpg'. Unknown format!

crystalspace.maploader.parse.texture:
Could not load texture 'TEXP1013493.jpg', using checkerboard instead
[node: world,textures,texture(name=TEXP1013493.jpg)]

crystalspace.maploader.parse.image:
Could not load image 'glossy.png'. Unknown format!

crystalspace.maploader.parse.texture:
Couldn't load image 'glossy.png', using checkerboard instead!

crystalspace.maploader.parse.image:
Could not load image 'black.png'. Unknown format!

crystalspace.maploader.parse.texture:
Couldn't load image 'black.png', using checkerboard instead!

Other notable clues are the following warnings I get when running the program:

Code:

WARNING: could not load plugin 'crystalspace.window.x.extf86vm'

crystalspace.pluginmgr.loadplugin:
could not load plugin 'crystalspace.graphics3d.shader.glcg'

This was working before so I would guess I'm somehow missing a package or something didn't get set up but the configure script before I built Crystal Space. Unfortunately, I'm not knowledgeable to diagnose what it might be. Does anyone have a suggestion?

Thank you,
Sal
