Woops.

It turns out that I missed a blatantly obvious error message which 6.2.1 
did not give:

================================================================
Starting program: c:\data\source\ghc\grass/./objectio/geo.exe
grass/./objectio/geo.exe: main.hs:23:8-70: Irrefutable pattern failed 
for patter
n [fileMenuID, mapMenuID, grassDBMenuID]
================================================================

after I shortened a list of ids.

Luckily this afternoon I took delivery of a pair of reading glasses 
which will hopefully help me to avoid such errors in future.  Thumbs up 
for that installer.


Cheers
