[SDL] SDL_Image installation can't find SDL

[CB]

I installed SDL 1.2 on my Mandrake 8.0 system with no problems (source code 
version--couldn't get the .rpm to install). I then tried to install 
SDL_Image 1.2 but it says it can't find SDL. The FAQ's didn't really cover 
this problem, but I did try a couple of related suggestions, namely:

Edit the file /etc/ld.so.conf, and make sure it contains the line:
/usr/local/lib

(I assume you just put that line after the one that's in there. IOW, It 
doesn't replace the one in there, right?)

Also made sure /usr/local/bin was in the path.

I tied installing a game I had downloaded that needed both. It seemed to 
see SDL, but of course halted when it couldn't find SDL_Image.

Any other suggestions?

TIA
