Cloneticket-Withdata on rt 3.8.8: patchfile still required?

Hi everyone,

when installing the extension Cloneticket-WithData on rt 3.8.8 (running
on Debian Linux) I fail to install the included patchfile for rt 3.8.
(named patch_on_rt_3.8)

My questions:
Is it still necessary to use the patch? A lot of the changes seem to
have made it to the rt-files already anyway.

I they are still needed did anyone successfully patch? My tries with
adding the changes manually were all unsuccessfull.

Thanks for any help!
