installed GRASS on Windows with cygwin
by following the directions at http://geni.ath.cx/grass.html
on one of the campus laptops

EPSG:32045 - NAD27 / Vermont 
EPSG:32145 - NAD83 / Vermont

g.proj - Unable to locate component.
The application has failed to start because pq.dll 
was not found.  Re-installing the application may fix this problem.

.. so I reinstalled grass and got the same error.

Googling the error suggests that "pq" is postgres related, and
so I've tried re-installing that, with "src" checked 
(just because it wasn't last time).

Found a remark at http://geni.ath.cx/wiki_grass.html
that pq.dll is now named cygpq.dll;
comment says to copy cygpq.dll to pq.dll.
A file search found it at c:\cygwin\bin\cygpq.dll
 Start -> Run... "cmd"
 > cd c:\cygwin\bin
 > copy cygpq.dll pq.dll

Asked for number of NAD83, showed list (space, q); 
I chose "default" - looks like it worked.

It created a ~/grass_data directory
as well as ~/grass_data/newLocation       (what I called the new data set)
and ~/grass_data/newLocation/PERMANENT/   (default given by directions)

Launching it again gives two windows :
 1) is a grass30 unix shell
      GRASS 6.0.0 (newLocation):~ >
 2) is a GUI that says "GRASS 6.0.0 GIS Manager - newLocation"
    with menus for
    File, GIS, Display, Raster, Vector, Image, Grid3D, Database, Help
    as well as a bunch of icons and two panes.


===================================================

So at this point I have a grass system (unix command line + GUI) 
running on both thirty and one of the windows laptops.
thirty has some sample databases and a pointer to a tutorial.

user/pass: toor/root on laptop with "grass" label
