[GRASS-user] Why does g.extension fail...?

[sgw00412 at nifty.com]

Dear grass users

I succeeded in installing d.barb the other day.

Because d.barb was very wonderful addon, I tried installing to other PC. 
However, I fail in the installation....

I tried on the following conditions. 

(Case 1) ubuntu11.04 wubi version on Windows7
---> Success

(Case 2) ubuntu10.04 vmware version on Windows X
---> failed

(Case 3) lubuntu11.04 vmware version on Windows 7
---> failed

In Case 2 and 3, the same error message is output as follows.
The log might not be read easily for you in a Japanese mode...

I don't understand that though there is '/usr/lib/grass64/bin/', error messege
 'can not stat' output..

I tried all cases by user and root(su).

I changed to permission of '/usr/lib/grass64/' from read only to read and writ
e . Of course, 
I also corrected two make files in all casees;
/usr/lib/grass64/make
Platform.make
Grass.make

I want you to give profitable information by all means...
Or, please teach other installation method.
