[GRASSLIST:9031] Re: v.in.ascii error

[Tiago Salgueiro]

My problem is not running v.in.ascii. This command works fine but after,
when I tried v.surf.rst the program gave this warning and ask me to run
v.build. I did that and tried v.surf.rst again. Now program didn't ask to
run v.build but the error appears. Can it be some parameter wrong in
v.surf.rst command??

Thanks,
Tiago
