Ugh, top-posting...  Reformatted.

One thing to keep in mind (and which people trying to make Cygwin CDs
using setup.exe keep forgetting) is that setup.exe is not a mirroring
tool.  It will not download packages that are already installed on the
system, even in download mode.  So, if you have "the package that contains
cygpopt-0.dll" (see below) installed on your system, but the tarball for
it is somehow missing from your package cache, it will not be
re-downloaded.  If you want to make setup download stuff, move your Cygwin
directory out of the way before downloading (you can move it back
afterwards without any loss of information -- just delete the
newly-created Cygwin root folder).

> What package contains the dll?

As Eric said, "cygcheck -p" should work for a sufficiently recent version
of Cygwin (1.5.19+).  Otherwise, there's always the Cygwin package search
page at <http://cygwin.com/packages/>.

Unless you store plaintext passwords in the environment, nothing in the
cygcheck output should be a security hole.  However, we should probably
have an FAQ page on what can be sanitized in the cygcheck output and how
to sanitize it without losing information...  Any volunteers? :-)

It is for Cygwin 1.5.19 or newer.
HTH,
