  Nope. /usr/local/grass5/dev is a shell script, not a directory.

  See above. There is no create_fifos.sh because there's no directory called
dev/. It's a shell script file.

  Most source files I can compile and make as a user, then it requires root
access to run 'make install'. That was the case here, too. Only root has
write permission to /usr/local/

  I understand, too, there are now permission problems, and only the mapset
owner can work with those files. IMO, that's not a good thing. Leave the
*nix permissions to do their thing and let local administrators modify
access groups to suit their needs and security philosophy.

  /usr/local/grass5/dev is owned by root:

-rwxr-xr-x   1 root     root          977 Feb 16 16:27 dev*

  When I try running, `./dev /usr/local/grass5', nothing meaningful happens:

touch: /usr/local/grass5/dev/fifo.15b: Not a directory
rm: cannot remove /usr/local/grass5/dev/fifo.16a': Not a directory
touch: /usr/local/grass5/dev/fifo.16a: Not a directory
rm: cannot remove /usr/local/grass5/dev/fifo.16b': Not a directory
touch: /usr/local/grass5/dev/fifo.16b: Not a directory
rm: cannot remove /usr/local/grass5/dev/fifo.17a': Not a directory

All because dev is a file, not a directory.

  Something's quite broken here.
