Hi Massimo,

it is a more genera decission.

Scintific Linux, Apache etc have TCL 8.5 as default.
If we want to support them (with Rivet 3), it has to build here.

I may add a switch that TCL must have 8.6.1 minimum.

The current spec file says:

%define use_newer %(echo 'puts [package vsatisfies [info patch] 8.5.10]'
| tclsh)
Name:           apache2-mod_rivet
%if %{use_newer}
Version:        3.0.1
Version:        2.0.6

So, we may add a switch case to use 2.3.4 from 8.5.10 to 8.6.0.

About the try command: I normally have a compatibility layer to emulate
new commands by a tcl command, if I am forced to support older interpreters:
if {0 == [llength [info commands ::try]]} {
        proc ::try args {...}

There is no tcl equivalent of try in the wiki, strange...
There was one in the TIP 329, but the link is dead.

Thank you,
