The plugin needs permission to bind to port 68 (ie, needs to be running
as root).  When you ran it from the command line, it was running as
root, and therefor worked.  Your nagios installation probably isn't
running as root, and therefor the plugin isn't either.

Perhaps you could work around this by making the check_dhcp plugin SUID
root, and only executable by the nagios group?  This would help prevent
possible security issues in the check_dhcp plugin, but would allow it to
bind to port 68.
