Networker 6.0.1 error /usr/lib/dld.sl: Unresolved symbol: acl (code)

[goeze]

I updated one client from 553 up to Networker version 6.0.1. Since this time I get error messages which looks like this:
client:/opt /usr/lib/dld.sl: Unresolved symbol: acl (code) from /opt/networker/bin/save
* client:/opt /opt/networker/bin/save: exited on signal 6

/usr/lib/dld.sl:

So I'm not sure if this is an HP-UX problem or an Networker error. With the old version of Networker I did'nt have any problems.
I searched on HP's web page but there was nothing appropiate. Does anyone have an idea ???
