Crossfire - Openwindows

Are there anyone here proficient enough with OpenWindows to know what
went wrong when a person trying to compile crossfire 0.88.5 got the
following error:

> convertfont crossfire.bdf
> crossfire.bdf->./crossfire24.fb
> cp crossfire.bdf /private/games/crossfire/fonts
> cp crossfire.fb /private/games/crossfire/fonts
> bldfamily -d /private/games/crossfire/fonts
> * crossfire            /private/games/crossfire/fonts/crossfire.ff (Encoding: unknown)
