It would be better to build without so many packages disabled... You're definitely going to run into trouble.

Thanks for the immediate nearly instant help, you're awesome! Sorry that I couldn't get back to you as fast as you came up with the patch, Krita takes a while to compile on my machine(s). I can confirm that the patch you've provided fixes the issue. I disabled as much as I could for testing purposes, however as Exherbo is a source-based distribution like Gentoo we offer a few options to enable/disable optional features on compile-time.
Cool, I'll push the patch.
