Do you mean $s is not set?  I can successfully call methods on it that 
output httpd.conf settings like $s->keep_alive.

I've had the chance to hack on this again and I think I see what you are 
saying here.  As a followup, basically what I'm trying to do is define a 
command parameter such as

MyappRoot /path/to/myroot

  in the global server config and then

PerlConfigRequire '/path/to/app/lib/My/'

which builds the command parameter like

Apache2::Module::add( { name => 'MyappRoot', ... } );
sub MyappRoot {
   my ($cfg, $parm, $arg) = @_;
   $cfg->{_myapproot} = $arg;

so that in I can grab MyappRoot like so:

use Apache2::Module ();
my $cfg = Apache2::Module::get_config('My::Config', Apache2::ServerUtil);
my $approot = $cfg->{_myapproot};

and then do some initialization using $approot, and possibly other 
command directives, so that all my configuration is set by command 
directives.  See the additional email on this thread I just responded to 
for the other approach I tried.

The parent I believe, since this is during startup.

I'll check these out.  Thanks for the continued help.
