Try this: create a merged.psgi file with this content:

use Plack::Builder;
use App1;
use App2;

builder {
  mount '/app1' => App1->dance;
  mount '/app2' => App2->dance;
};


And then use it on Apache with:

<Location />
    SetHandler perl-script
    PerlHandler Plack::Handler::Apache2
    PerlSetVar psgi_app /path/to/merged.psgi
</Location>

I have not tested this, I don't have a mod_perl2 at hand anymore, but it
should work.

Bye,
