Puppet users - Sep 2013 - Some php5 extensions not installed until a second run

Hi, I''ve inherited a puppet setup for automating php installation and 
extension management.  We''re on Debian and we''ve encountered a
strange
issue that I''ve traced down back to puppet I think. I''ve
stripped back the
configuration and made the problem reproducible, logs and config pasted 
below. 

1. php5-common, php5-memcache, and php5-mysql are all installed. 
2. php5-common and php5-mysql receive an update, say from 5.3.3-7+squeeze14 
to 5.3.3-7+squeeze17
3. Puppet runs and php5-common upgrade conflicts. Apt''s first solution 
removes php5-mysql and php5-memcache. 
4. Puppet continues run and re-installs/upgrades php5-mysql. It skips 
php5-memcache.
5. On a subsequent run php5-memcache is installed again as expected. 

This appears to only happen to packages that don''t share the php5
version
naming schema, but that may be just a clue, not a cause. e.g. php5-memcache 
is 3.0.4-4+squeeze1. 

I have: 

   package { "php5-common": ensure => latest }
   php_module { "mysql":
      ensure => $php5_mysql ? {
         ''1'' => ''enable'',
         ''0'' => ''absent'',
      },
   }
   php_module { "memcache":
      ensure => $php5_memcache ? {
         ''1'' => ''enable'',
         ''0'' => ''absent'',
      },
   }
   define php_module ( $ensure = ''enable'' ) {
      if $ensure == "enable" {
         package {
           "php5-${name}": ensure => latest,
           require => [ Package[ ''php5-common''],  Package[
''php5-cgi'' ],
Package[ ''php5'' ], Package[
''libapache2-mod-php5'' ] ],
       }

      } else {
         package { "php5-${name}": ensure => absent }
      }
   }

In the debug of a run, I see (relevant lines only):

So, why, on line 547, when memcache is definitely not installed does it not 
install it? I''ve been on this for 3 days and am officially stumped. Any
help would be appreciated.
