 |      tar/pax doesn't dearchive correctly long symlinks from a pax_restricted

 | mono-1.2.6.tar: POSIX tar archive
 
 This is not a bug. Whatever pkg_create builds:
 1. Should be marked as a GNU tar archive not as a POSIX one.
    POSIX tar archives don't have ././@LongLink extensions.
 2. The extension string is "././@LongLink" not "././@LongSymLink". pax
    checks for the exact name, others might check for "././@Long" or something
    that is why they work.
