Slink_cd dependency checking is broken

[Steve Dunham <dunham@cse.msu.edu>]

The dependency checking in slink_cd is rather broken.  pkg-order loads
the /var/lib/dpkg/status file before doing dependency checking.  

An example of the problem: The i386 and sparc CDs were created on
systems with "whiptail" installed, so pppconfig ends up on CD1 and
whiptail ends up on CD2.  (pppconfig depends on whiptail.)

Doing:


./pkg-order --nocheck-conflicts --nooutput-order --check-recommends --installed-packages /tmp/FOO /archive/tmp/Packages-main.1

gives:

======================================================================
Unknown:
   Package: alsa-modules
      whiptail
   Package: pppconfig
      whiptail
======================================================================
2 Critical errors encountered. Exiting.

Where /tmp/FOO is empty.  (For some reason /dev/null doesn't seem to
work.)

Also, Steve, the correct shell syntax is: ">filename 2>&1", rather than
"2>&1 >filename".  (The former pipes everything to to the file, and the
latter points stderr to the file that 1 points to and then points 1 to
"filename", leaving stderr going to the former stdout.)
