fife.fife.CannotOpenFile: _[CannotOpenFile]_ , File couldn't be opened 
:: content/fonts/Unifont.ttf (Couldn't open content/fonts/Unifont.ttf)

The root problem is a missing font or font format. I tried a simple 
rebuild of the package, but it had no effect. Looks like the font path 
is part of the source code, so might be more font references with 
similar issues.
