There is a new pull request by abenson against master on the void-packages repository

https://github.com/abenson/void-packages np_gef
https://github.com/void-linux/void-packages/pull/22481

[WIP] New package: gef-2020.03.1
1. I don't like that keystone python bindings require patching
2. I've already submitted an issue upstream to not use `-` in versions
3. Even if `gef` drops off this PR (understandable) the new packages and changes to existing packages are necessary for it.

A patch file from https://github.com/void-linux/void-packages/pull/22481.patch is attached
