Issuses about Package XML configuration file once checked into TFS. When checked out into a difference box, warning occurs

hi folks:

  I've used XML package configuration in my packages in order to populate key variables. The configuration String is pointing to

a local folder in my machine. After that, I've checked my whole solution into TFS.  I did check the checked in file but could not find the .dtsConfig XML file.

  The problem occurs when the other teammate checked out this solution from TFS into his own box. When he tried to open the solution, it gives warning (not error though) saying it could not find the package configuration file . This totally makes sense as his local machine does not have the same URL I had in my  box. 

  In situation like this, how can we fix in the multi-developers SSIS environment ? 

 Thanks

Hui
