How to preserve patches to MacPorts base during "sudo port selfupdate"?

[MK-MacPorts at techno.ms]

Hi MP devs,

currently I have to have patch [1] in place to be able to successfully install qmake-based ports.

The problem is now that during "sudo port selfupdate” all these changes get reverted.

How can I keep my needed patches for MacPorts base without the need to re-patch base after the selfupdate call?
 
Greets,
Marko
