Grass, Versions, Packages, How to?

I recently installed cygwin, and the program Grass running under it, on a
computer with Windows XP Professional. Everything seemed to go fine.
However, I can start Grass and select a mapset from the initial screen.
Then, when I tell it to "Enter Grass" I get an error message in a window
labeled " Unable to locate component" and the error message says
libgrass_gis.6.1.cvs.dll was not found.

I looked for this situation on the various Grass mailing lists, found others
with this problem, and found one suggestion to install a newer version of
Grass. Although I downloaded and installed cygwin only a week or two ago,
and the latest version of Grass is 6.0.2 (released in FEB-06), my version is
6.0.0 (at least the screen says this), which is over a year old. So to fix
the problem, I want to locate and download 6.0.2.

I don't get how cygwin packages work. Do I somehow ask cygwin to find and
download this version. Ordinarily, with Windows binaries, I'd just google
for the file, download the zip, uncompress, and install. With Unix programs,
it's even easier: download, tar, and maybe move the files under /usr/bin.

Can anyone suggest the best strategy for attacking the problem? In order of
increasing difficulty, I can see these options:

1. Fix a path or move the dll file to where Grass expects it (assuming I
have the file).
2. Find and download the dll file and put it where Grass will find it.
3. Find and install the newer version of Grass.
4. Reinstall the old version and keep fingers crossed. (How does one
reinstall under cygwin?)
5. Reinstall cygwin, including the Grass package, as was done originally.

Which one do I have to use?
