While your wandering around in the device sub-tree, check for:
Code:
core2quad ~ $ ls -l /dev/std*
lrwxrwxrwx 1 root root 15 2012-11-07 09:51 /dev/stderr -> /proc/self/fd/2
lrwxrwxrwx 1 root root 15 2012-11-07 09:51 /dev/stdin -> /proc/self/fd/0
lrwxrwxrwx 1 root root 15 2012-11-07 09:51 /dev/stdout -> /proc/self/fd/1
Those sym-links are required but are sometimes missing.
