I have narrowed the problem down to this:

[EMAIL PROTECTED]:~$ /usr/local/bin/halcmd help
Segmentation fault

[EMAIL PROTECTED]:~$ su
Password:
[EMAIL PROTECTED]:/home/andy# /usr/local/bin/halcmd help
Use 'help <command>' for more details about each command
Available commands:
  loadrt              Load realtime module(s)

then the rest of the help output follows.

As you can see, it works for root but not for a regular user. I'm
guessing there is a setup step missing.

Any ideas on how to solve this? Thanks!
