I think ogr2ogr does what I want - it looks like it has a driver for 
putting the contents of various formats into database (including MySQL 
which is already being used for the wildlife database) and then I can 
probably get the coordinates I need to draw the county border and 
lakes/rivers from there.

With respect to other GIS apps - after building Fedora 9 versions of 
qt3,qt4,sip,PyQT4 - and grass from a spec file (slightly modified) 
grabbed from a Fedora SVN server, I was able to get qgis to build from a 
slightly modified spec file that targets Fedora.

Haven't played with grass or qgis yet, though, but hopefully they aren't 
too hard to figure out and I can start learning more about GIS.
