SharePoint - Problem provisioning a master page through a solution/feature

I cannot find out why a master page is not being provisioned to /_catalogs/masterpage as (I suppose) I'm directing it.

Here are the relevant snippets:

.ddf:

;*** Master page
..\..\..\Feature\TEMPLATE\FEATURES\ADS\MasterPage.xml ADS\MasterPage.xml
..\..\..\Feature\TEMPLATE\FEATURES\ADS\MasterPages\ADS.master ADS\ADS.master

MasterPage.xml:

<开发者_StackOverflow社区Module Name="MasterPages" List="116" Url="_catalogs/masterpage">
    <File Url="ADS.master" Type="GhostableInLibrary" />
</Module>

Feature.xml

<ElementManifest Location="MasterPage.xml" />

I expect ADS.master to end up in http://mySite/_catalogs/masterpage, but it doesn't.

Ideas, appreciated. Thanks in advance.

Note: I looked already at this post, but I'm manually editing these files. Maybe what I'm looking for is how those files look after gen'ed by WSPBuilder.

Did you activate the feature?

Did you check if the feature files end up in the right place in the 12 hive?

WSPBuilder does not do anything with these files, it just packages them for you.. you shouldnt have to use a ddf?
