Exactly what I was expecting. The ki-repo hasen't been updated since Februry 22 and you're trying to combine it with pkgsrc-current.
Hence, version mismatching.
You could try the current build in https://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/amd64/9.0_current/All/ but, it will be a hunt trying to find the corresponding tarball of pkgsrc, since this build was done on May 26.
As I see it, right now you have two choices:
1) Sync with 2020Q1
2) Wait a few days (weeks?) until the 2020Q2 builds are uploaded
What would you like to do? I will provide instructions depending on your choice.
Btw, I can reply in portuguese if that would be helpful?
