Hi this is Abhay Menon, I am facing a problem with r.terraflow module. 

I am using Fedora Core 4 as the OS. also I compiled the module with --enable-largefile
switch. and my dataset in ESRI Ascii Raster Grid.

as soon as it starts is generating the watersheds and watershed graph.
the following message is displayed.

r.terraflow has an option 'STREAM_DIR'. It defaults to /var/tmp.

Are the access rights set so that you can create dirs and files and read from
them in your /var/tmp?

Only a guess, let me know if it helps.
