Puppet users - Apr 2012 - using array parameters with inherited parameterized classes

I am trying to use an inherited  array parameter in a parameterized
class as follows:

<puppet>
class params{
  $packages = $operatingsystem ? {
    Centos => [''scons'',''bzip2''],
    Ubuntu => [''scons'',''bzip2''],
    # Ubuntu => ''scons'',
  }
}

class depacks(
  $packages = "$params::packages"
) inherits params {

  package{ $packages:
    ensure => ''present'',
  }
}

class {"depacks": }
</puppet>


* It''s failing with following error:
<error>
err: /Stage[main]/Depacks/Package[sconsbzip2]/ensure: change from
purged to present failed: Execution of ''/usr/bin/apt-get -q -y -o
DPkg::Options::=--force-confold install sconsbzip2'' returned 100:
Reading package lists...
Building dependency tree...
Reading state information...
E: Couldn''t find package sconsbzip2
</error>

* It works fine if I override the inherited array parameter while
calling/evaluating the class:
<puppet>
class {"depacks":
 packages => [''scons'',''bzip2''],
}
</puppet>

I am using Puppet 2.6.14 with Ruby 1.8.7. The error occurs on both
Ubuntu and CentOS systems.

Am I missing something here? Any pointers will be really helpful.

Putting quotes around $params::packages is making $packages a string 
rather than an array.  Remove the quotes and it should work
