FreeBSD Port: enscript-letter-1.6.1_1

[Bob Perry]

I had some difficulty reviewing the man files.  Using unzip left me with the
following message:
    End-of-central-directory signature not found.  Either this file is not a
zipfile, or it                 constitutes one disk of a multipart
archive...
    unzip: cannot find zipfile directory in one of enscript.1.gz or
enscript.1.gz.zip, and cannot     find enscript.1.gz.ZIP, period.

Also had difficulty using zcat.

Please advise.
