Bug#731988: libpoet-perl: Error while loading ... app.psgi: Can't locate Plack/Middleware/Debug.pm in @INC

[David Christensen]

Package: libpoet-perl
Version: 0.11-1
Severity: normal

Dear Maintainer,

I installed libpoet-perl and am attempting to follow along with the
example in Poet::Manual::Intro.  Creating the application appears to
have worked:

2013-12-11 17:03:06 dpchrist at desktop ~/sandbox/perl/poet
$ poet new MyApp
my_app/.poet_root
my_app/t
my_app/logs
my_app/lib/MyApp/Mason.pm
my_app/lib/MyApp/Conf.pm
my_app/lib/MyApp/README
my_app/lib/MyApp/Log.pm
my_app/lib/MyApp/Mason/Compilation.pm
my_app/lib/MyApp/Mason/Request.pm
my_app/lib/MyApp/Mason/README
my_app/db
my_app/data
my_app/comps/index.mc
my_app/comps/Base.mc
my_app/comps/tmp
my_app/conf/local.cfg
my_app/conf/global.cfg
my_app/conf/layer/production.cfg
my_app/conf/layer/development.cfg
my_app/conf/dynamic/gen.pl
my_app/static/images
my_app/static/css/style.css
my_app/static/js
my_app/bin/get.pl
my_app/bin/app.psgi
my_app/bin/run.pl
my_app/bin/tmp

Now run 'my_app/bin/run.pl' to start your server.


Starting the server generates the subject error message:

2013-12-11 17:05:30 dpchrist at desktop ~/sandbox/perl/poet

Browsing to http://localhost:5000/ in Iceweasel implies that the
application server is not running:

Unable to connect

Iceweasel can't establish a connection to the server at localhost:5000.

The site could be temporarily unavailable or too busy. Try again in a few
moments.
If you are unable to load any pages, check your computer's network
connection.
If your computer or network is protected by a firewall or proxy, make sure
that Iceweasel is permitted to access the Web.


The suggested package libplack-middleware-debug-perl does not appear
to exist:

2013-12-11 17:33:19 dpchrist at desktop ~/sandbox/perl/poet
$ apt-cache search libplack-middleware-debug-perl

2013-12-11 17:33:27 dpchrist at desktop ~/sandbox/perl/poet
$ 


I prefer not to install packages from CPAN because of the risk of
destabilizing my system.


David
