DEFAULT_FONT_PATH=/usr/local/lib/tex/fonts/pkIf your fonts reside in a different location, you either need to install a symbolic link, e.g.
DEFAULT_SUBDIR_PATH=/usr/local/lib/tex/fonts/**
DEFAULT_VF_PATH=/usr/local/lib/tex/fonts/vf
ln -s /some/font/directory /usr/local/lib/tex/fonts/pkor set the environment variables, e.g.
setenv XDVIFONTS /some/font/directory(The environment variables corresponding to the other two above precompiled options are TEXFONTS_SUBDIR and XDVIVFS )
If all else fails, return to the xhdvi source
