SCOM: CU4 and Microsoft.SystemCenter.Library.mp 6.1.7221.61

This blog post is for those who updated SCOM with CU4 and have issues with the Authoring Console and Microsoft.SystemCenter.Library.mp version 6.1.7221.61.
-----------------------------
** Update: 08/09/2011 **
Microsoft published a KB-article which resolves this problem:

-----------------------------

After applying CU4, Microsoft.SystemCenter.Library management pack is updated.
When using the Authoring Console on MP's created in a CU4 Management Group, you are prompted for Microsoft.SystemCenter.Library.mp 6.1.7221.61.

But, the MP file is not available from the CU4 installation sources.

The management pack is updated trough the sql batch on the OperationsManager database, CU4_Database.sql.

DECLARE @ver nvarchar(25)

DECLARE @compare int

SET @ver = (SELECT Mpversion FROM ManagementPack WHERE MPName = 'Microsoft.SystemCenter.Library')

-- Update Microsoft.SystemCenter.Libarary MP directly via SQL

A thread about this is going on at the Microsoft forums: http://social.technet.microsoft.com/Forums/en-US/operationsmanagermgmtpacks/thread/45d6bac1-4b10-4f36-86de-2efea895fc94

There is an easy workaround mentioned on the forum by dbabob56:
After exporting you can change the version number.
