Thanks Gustaf,
That got me past the immediate problem - but I'm now seeing some
further issues which I can't fully explain.
1. Tcl8.5 only - After clock scan : invalid command name
"::tcl::clock::scan"
2. Tcl8.5 & Tcl8.6 After ::try .. on error : can't read "magicCodes":
no such variable
The errors only seem to happen after the commands are executed on
startup within ns/tcl
actually, i cannot reproduce this problem (while i could reproduce the
original "::try" issue
with Tcl 8.5.19). The underlying problem is that Tcl does some
optimization upon
initialization of Tcl, assuming a certain initialization sequence. The
order on vars,
procs and namespaces in NaviServer is more or less random (depending on
hash
table populations).
So, i think, it is the best strategy for NaviServer to put the fingers
away on stuff
coming from Tcl. The "clock" command seems to populate as well the ::msgcat
namespace (it would be better if it had been named ::tcl::msgcat). When
"clock" is called
during initialization (where content for the blueprint is collected),
then NaviServer puts
this as well into the blueprint. I have made now a modification [1] to
exclude the ::msgcat
namespace as well. All my test continue to work, maybe this is some
improvement
for the problem in your configuration.

When attempting to use the tip version of NaviServer, whenever we
use the tcllib's ::try command (which we need because we're
running Tcl8.5) we get an error: "unknown namespace in import

I've tried to simplify the testcase as much as I can to the
following under Debian Stretch. The error also occurs under
Debian Jessie.
Dear David,
you might try the following change

thanks for the good test specification and case!
