[Module-build-general] no prereq detection with Module::Build->dispatch

[Jos I. B. <ka...@xs...>]

Hi, i'm trying to add proper module::build support for CPANPLUS, but 
i'm getting quite confused by the docs. On top of that, i think i've 
run into a bug:

[kane@coke ~...Perl/mb_test]$ cat mb.pl
use Module::Build;
use Data::Dumper;
chdir 'Class-DBI-ToSax-0.09';
my $m = new Module::Build (module_name => 'Class::DBI::ToSax' );
$m->dispatch('build');
print Dumper $m->{properties};

[kane@coke ~...Perl/mb_test]$ perlc mb.pl
Checking whether your kit is complete...
Looks good
$VAR1 = {
           'script_files' => [],
           'build_script' => 'Build',
           'perl' => '/opt/perl/bin/perl',
           'build_requires' => {},
           'dist_name' => 'Class-DBI-ToSax',
           'base_dir' => 
'/Users/kane/Documents/Perl/mb_test/Class-DBI-ToSax-0.09',
           'module_name' => 'Class::DBI::ToSax',
           'conflicts' => {},
           'requires' => {},
           'recommends' => {},
           'config_dir' => '_build',
           'dist_version_from' => 'lib/Class/DBI/ToSax.pm',
           'dist_version' => '0.09'
         };

as you can see, it's not detecting any prerequisites...
however, seeing the Build.PL:

Module::Build->new(
     module_name => 'Class::DBI::ToSax',    license     => 'perl',
     requires    => {
         # Bug in 5.6.0 isa()...
         'perl'       => '5.6.1',
         'Test::More' => 0,
         # Both of these are required by Class::DBI, so shouldn't be too
         # onerous...
         'Class::Accessor'          => 0,
         'Class::Data::Inheritable' => 0,
         # DCONWAY rocks.
         'NEXT' => 0,
         # Most people will want this and it's good for testing.        
'XML::SAX::Writer' => 0,
     },
)->create_build_script;

i've tried this for a few more modules, but none of them come up with 
the prereqs.

A few more questions though.
* With a normal installation, one would do:
	perl Build.PL
	perl Build
	perl Build test
	perl Build install

this translates to the following dispatch table:
	build
	test
	install

what action for 'dispatch' is equivalent to 'perl Build.PL' ?
is that the new call? i don't see that documented....

* Is there a nicer way to get the prereqs out of the $m object, rather 
than poking into it?
