Subject: v.surf.rst fails when called from GUI and in command-line mode

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources
GRASS Version: 6.0 beta2

Calos Henrique Grohmann

code: grass6.0beta2.

When I try to call v.surf.rst from the GUI, when I
click over it I get:

child process exited abnormally
child process exited abnormally
   while executing
"exec -- v.surf.rst >@ stdout 2>@ stderr"
   ("eval" body line 1)
   invoked from within
"eval exec -- $cmd $args >@ stdout 2>@ stderr"
   (procedure "run" line 2)
   invoked from within
"run v.surf.rst"
   invoked from within
".#menubar.#menubar#menu3.#menubar#menu3#menu26 invoke active"
   ("uplevel" body line 1)
   invoked from within
"uplevel #0 [list $w invoke active]"
   (procedure "tkMenuInvoke" line 47)
   invoked from within
"tkMenuInvoke .#menubar.#menubar#menu3.#menubar#menu3#menu26 1

v"

   (command bound to event)

and in the terminal:

ERROR: Required parameter <input> not set:
   (Name of the vector file with input data).

but how could I give the input if the window didn't even open?
NOTE: according to Moritz Lennert, it could be a problem with how the module is called by the GUI (it is called via the "run" procedure and not "execute" like v.surf.idw)

and, If I try to call it from the terminal:...

the points are there, inside the region, so how could it not find them???
