Your profile says you are running SuSE 8.2 Personal. I am not sure, but I think that pkg-config is in the devel portion of the distribution. I am also not sure how much of the development libraries the Personal edition contains.
Try this. Fire up YAST and get it to the point where you can add new software. Look through the devel group of applications to see if you can find pkg-config (be sure of the spelling!). If you find it, install it.
If you don't find it on your disks using YAST, you will have to do it the way your ancestors did. Go to www.freshmeat.net
and search on "pkgconfig". That should take you to http://www.freedesktop.org/software/...fig/releases/,
where you will find the source for pkg-config. Untar it, read the INSTALL document and the README, and compile and install it.
I'm thinking you'll find it on the SuSE disks though, so it shouldn't be too much trouble. Let us know how it goes.
