This is the relevant error:
> /usr/local/grass-6.1.cvs/scripts/v.in.e00: line 175: e00conv: command 
> not found

You need e00conv (and avcimport) installed as e00 is not supported by
GDAL (yet). Get them from  http://avce00.maptools.org/


There should have been a test to make sure you have them installed but
it seems to have failed. This is on Cygwin, right?

I've just updated the test:

was:
E00CONV=`which e00conv`
if [ "$E00CONV" = "" ] ; then

is now:
if [ ! -x "`which e00conv`" ] ; then


I think the string compare fails on Cygwin and generally you need to do
instead:
if [ -z "$E00CONV" ] ; then


The "! -x" I did above is just a simplification of the two lines.
(this is not an executable file of that name/path)

Could you test the CVS version of v.in.e00 and see if you get the error
now? (or just some command line tests?) If so we can get that fix in for
6.0.2 so others don't suffer the same problem.


We don't currently but probably should check the exit code of those
commands (with "$?") to make sure it all went ok.


The following scripts also do the [ "$x" = "" ] test, if I am right about
it not working on cygwin then they all need updating to [ -z "$x" ].

$ grep -rI '""' scripts/* | cut -f1 -d/ | sort | uniq
