New symfony plugin: PEAR parsing error

When I try to upload a PEAR package for a new plugin to the symfony plugins site, I receive the error

An error occured while parsing ynWidgetAjaxAutocompletePlugin-0.1.0b1.tgz (The archive "ynWidgetAjaxAutocompletePlugin-0.1.0b1.tgz" does not follow PEAR conventions).

What might be the problem? My package.xml validates with pear package- v开发者_高级运维alidate. It is at http://pastebin.com/aeXEG6Y8

UPDATE: I've rebuilt the package.xml with pfm, but still the same error: http://pastebin.com/R4799KNY

Thank you!

I suspect the package.xml is not at the correct place in the tgz archive.

You should package up your package file by using

$ pear package

because it will put package.xml at the right place in the archive.
