Thanks for the quick reply!
I'm afraid I have to sleep before I read man truss & ktrace
& think what options you might want, but meantime I append truss output.
Really confusingly, with truss its just started working, viz
http://land.berklix.org/
Despite I tried to install a generic httpd.conf for the truss run.
Hmm, I'll come back to this tomorrow. Thanks !
