The second --with-prefix=... switch overrides the first.

That's because of the --prefix=/usr/local/ switch.

Possible reasons for this error are:

1. It couldn't figure out your username (does the "whoami" program
give the correct information)?

2. It couldn't create the /tmp/grass-<username> directory.

3. The /tmp/grass-<username> directory already exists, but you don't
own it.

4. /tmp/grass-<username> already exists, but it isn't a directory.

These are a direct consequence of the driver failing to start due to
the above error.

The dev directory and create_fifos.sh are only relevant if you used
the --enable-fifo switch (which only exists for compatibility reasons,
and shouldn't be used).
