SYmfony plugin upload error: You must specify the min version for symfony - plugins

Question

I have been trying to upload my SYmfony plugin for some time but I keep getting this error.
Initially the dependency on the SYmfony Package was missing, but I added that.
My package.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<package packagerversion="1.9.0" version="2.0" xmlns="http://pear.php.net/dtd/package-2.0" xmlns:tasks="http://pear.php.net/dtd/tasks-1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://pear.php.net/dtd/tasks-1.0 http://pear.php.net/dtd/tasks-1.0.xsd http://pear.php.net/dtd/package-2.0 http://pear.php.net/dtd/package-2.0.xsd">

<summary>sfActivateablePlugin allows auditing record activation/deactivation by setting up a flag, timestamp & user detail fields.</summary>
<description>The sfActivateablePlugin allows you to automatically:
* create a `is_active` flag (or name of your choice)
* create timestamp & user detail fields (e.g. `activated_by`, `activated_at`, ...)
* populate timestamps & user details when `is_active` flag is toggled on a record.</description>

Am I missing some tag? Or specified incorrect Symfony version? Pl help

Answer 1

Figured out a couple of mistakes:
1. the package name is symfony and not Symfony
2. the max version is also required
If you use the Pear Package Manager API:
$packagexml->addPackageDepWithChannel('required', 'symfony', 'pear.symfony-project.com', '1.4', '1.4', '1.4');
