Permissions Error (Could not stat() comman d file )

[Pascal Miquet]

Chris,

Using a RH8.0 distro, I've at least the same problem, and the same Idea
to use a RH7.3 rather the 8.0, cause on my laptop all things tested is
running fine.
Should use the GD function at least, but nagios and addons works pretty
good on an RH7.3

I didn't checks on RH for updates....
Regards
Pascal Miquet
