Comment:

 I've been delivering plugins with plugin dependency logic since April
 2012. I developed the "full" solution in the oik base plugin and provided
 lazy code in the dependent plugins.
 Since there's no core API, each plugin that has a dependency needs to
 deliver the same basic code. I tried to develop a solution that worked
 during activation; but that was a nightmare. I plumped for responding to
 "admin_notices".

 {{{
 add_action( "admin_notices", "oiku_activation" );
 /**
  * Implement the "admin_notices" action for oik-user
  */
 function oiku_activation() {
   static $plugin_basename = null;
   if ( !$plugin_basename ) {
     $plugin_basename = plugin_basename(__FILE__);
     add_action( "after_plugin_row_" . $plugin_basename, __FUNCTION__ );
     require_once( "admin/oik-activation.php" );
   }
   $depends = "oik:2.0-alpha.0329,oik-fields:1.18.0325";
   oik_plugin_lazy_activation( __FILE__, $depends,
 "oik_plugin_plugin_inactive" );
 }
 }}}
 See http://plugins.svn.wordpress.org/oik-nivo-slider/trunk/admin/oik-
 activation.php

 This solution works for dependent plugins which are: missing, inactive,
 not at the required minimum version. With the right API built into core
 the above code could reduce to a one line filter.

 Note: plugins which are dependent on others wait for the appropriate
 "plugin loaded" signal before attempting to use those plugins APIs.


 The challenge I now face is where the missing or out-of-date dependent
 plugin's repository isn't wordpress.org. e.g. oik-fields.  I have a
 similar challenge when it comes to determining which jQuery libraries are
 available!
