Sharepoint 2010 register control as safe through wsp

Question

I created a "Hello World" Sharepoint 2010 solution using VS2010. It contains just a feature, and a webpart containing a label. I registered the webpart as a safe control in the "Properties" window of the webpart, in VS2010.

When I deploy my solution to my local server, everything works great! I can add the webpart to a page, and in the web.config file my control is added to the SafeControls list. When I install the same solution on a different server, I can see the webpart in the list of available webparts, but when I try to add it to the page, it tells me that it's not registered as safe. When I check the web.config file, there is no entry for my control. If I add one manually (the one from my dev server), things start to work.

Now, I wonder why the control is not registered when I install the wsp file. The manifest inside the wsp contains this line:

<Assemblies>
<Assembly Location="abc.TestWebPart.dll" DeploymentTarget="GlobalAssemblyCache">
  <SafeControls>
    <SafeControl Assembly="abc.TestWebPart, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e262c75e6f6e8440" Namespace="abc.TestWebPart.VisualWebPart1" TypeName="*" />
  </SafeControls>
</Assembly>

Any ideas are very welcomed!
