Q1. 'Exec to compress' error - what do I do?
    ----------------------------------------

>Both when I save and load, nethack produces a 'Exec to compress
>save/502rodney failed.' error.

NetHack execs a compression program, either /usr/ucb/compress, or /bin/gzip,
so if you don't have one of those files, that will be the problem.

Solution:
  Make symlinks such that these files do exist, pointing to the actual
  locations of compress and gzip on your system.
     or
  Recompile with the COMPRESS variables in include/config.h changed.

Note:  nethack normally installs using non-user privileges, normal users
        must change the config.h otherwise.
