OpenGL isn't really an engine: it is a low level interface for drawing
individual polygons. If that's what you want it is fantastic, but if you
are looking for a higher level solution like a Quake-style engine, you'll
need to write a lot of more specialised code over the top of OpenGL (for
example, Quake itself uses OpenGL for actually drawing the triangles).

OpenGL is an abstract interface design rather than any specific library,
and there are many different libraries that implement this interface.
It sounds like the particular implementation that you downloaded is for
Windows, which is no use when you are writing a DOS program. Try getting
a copy of MESA (www.mesa3d.org) instead, although be warned that you
may need to do some porting to get this working with djgpp, since I don't
think the DOS version is being maintained by anyone at the moment.
