Yes, I have read this. I don't think I really know what i'm looking for in
step 2, which is why I believe I can't really accomplish step 3.

If I query RPM, it tells me I already have "libjpeg.so.6" installed. I this
the same as the jpeglib described in step 2? If not, where would I find
"jpeglib"? I believe one of the readme's I read said that the jpeg libs
that come standard with RedHat would be fine (I have RH 7.3).

So I believe if I understand where me jpeg libs are in step 2, I can point
at them when I make my imaging lib in step 3, and then everything should be
fine, right?

Can anyone offer a suggestion?
