Tux Racer

Has anyone here mangaged to play Tux Racer? ( http://tuxracer.sourceforge.net ) First I tried to install it from an RPM - it didn't work. (I have 3D acceleration, I can play other 3D games such as foobillard with no problems, so, this is not the problem) Then I tried to install it from the source, but the configure command says I don't have the tcl library, which I do have (on /usr/lib/tcl8.4 ) I try to use "./configure --with-tcl-libs=/usr/lib/tcl8.4" and it doesn't work either. Am I doing something wrong? Maybe I should try installing tcl again, this time not from an RPM? Dalton
