Have you actually tried setting the DISPLAY variable as the error
message says? That should take care of the error.
Also, have you tried not making your su session a login shell? If you
don't make it a login shell, your environmental variables should be
carried over from your user session instead of setting new values for
root. Hence, the DISPLAY variable will not be reset.

How is the CDROM mounted? Is it mounted with noexec? Have you looked
at the script to see what's supposed to happen at 307?

Same answer, except what in the world is a "fakeroot"?

Whatever works.

The question is, does it work? If it works, then don't worry about it.
And there's nothing old-fashioned about zcat. It's just one of the gzip
and gunzip family. Remember that it's the GNU version of tar that has
the z option where you can tar and zip together. The tar program on
other OSes, such as Solaris, don't have that option, so zcat and tar
used in that way in the only was to decompress the file.
