/usr/bin/groff and friends aren't packaged in groff-1.15-2 from
rawhide-release-20000130-1. The only members of the package are the bits
from /usr/lib/groff. This makes reading manual pages impossible:
% man pvm
Formatting page, please wait...
sh: /usr/bin/groff: No such file or directory
sh: /usr/bin/gtbl: No such file or directory
Ooops, will be fixed in groff-1.15-3.
Where's that brown paper bag?
