Strange though, I used the precompiled external libs for visual studio 2002, and they worked. (i've upgraded now)

Note, for other people having the same problems:

See - http://clanlib.org/download/binaries-win32-vc90/ for the external libs source code packages

Edit (in notepad) the .vcproj, and change [Version="9.00"] to [Version="7.00"] - This seems to work
