IIRC, /dev/port can only accessed by root. That's kernel policy and in
my mind correct, as you can do lot's of bas things if you have access
to that file.
So the question rather is, why libieee1284 can't use the
/dev/partport* files, which is the normal way to access the parallel
port.

Are such files created by the kernel automatically nowadays? If they
aren't, running MAKEDEV may help.
