/home/wsabey/Downloads/SDL-1.2.15/build/.libs/libSDL-1.2.so.0That happened to me in the past, that a library only installed the '.so.1' link, and a bunch of programs were looking for the '.so.0' version. So I checked for that already, and I don't think it's the file name that's the problem, the installer has created the '.so.0' link DF is looking for. I checked and it's world-readable (had that problem in the past too...), the next step would seem to be the path; you quoted '/usr/lib/' while I have it in '/usr/local/lib/', could that be causing problems?
EDIT: Yeah, I linked the library from /usr/lib/ and it's moved on to another file it can't find; libSDL_image this time. This isn't in /usr/local/lib/ either, can you suggest the package name / source location for this please?
