The error indicates that the temporary file couldn't be created.

Temporary files are created using the template:

	<database>/<location>/<mapset>/.tmp/<hostname>/<pid>.<unique>

where:

<database>, <location> and <mapset> are the values entered in the
startup screen; these correspond to the GRASS variables GISDBASE,
LOCATION_NAME and MAPSET respectively (run "g.gisenv" to check their
values).

<hostname> is the system's hostname, according to either gethostname()
(if it exists) or uname() (otherwise).

<pid> is the process ID of the process which is creating the file.

<unique> is a unique integer which is added to ensure that filenames
are unique.

Some questions:

1. Does the temporary files directory (.../.tmp/<hostname>) exist?

2. Do you have write permission for that directory?

3. Are there any files in that directory for which you don't have
write permission?

4. Do you have write permission for the mapset directory?
