Right, some environment variables aren't getting set correctly.

namely GRASS_WISH= is empty, and LOCATION= is empty for .gislock --

if a variable is empty it becomes "", ie nothing.

so if $LOCATION is empty:
 (from Init.sh)
# Check for concurrent use

becomes just "/.gislock", which is the wrong place to look.

can you try this at the xterm prompt:

cd /usr/local/grass-6.2.1/lib/
cygcheck /usr/local/grass-6.2.1/etc/lock.exe
cygcheck /usr/local/grass-6.2.1/bin/g.gisenv
cygcheck /usr/local/grass-6.2.1/bin/g.region

and look for any errors due to missing DLL libraries.

If you ever manage to make it into GRASS you can try "g.gisenv --help" at
the command prompt and see if you get a useful help message there.
That will tell you if most of the program is working.
g.gisenv is what sets $LOCATION.

can you try setting GRASS_WISH before entering GRASS?

at the xterm prompt:
GRASS_WISH=wish grass62

"which wish" at the xterm prompt should show
/usr/local/bin/wish   or  /usr/local/bin/wish8.4
