> I finally managed to make xbps-src move the needed files correctly without any sort of hack.

They aren't cleaned, however. xbps-src removes wrksrc after build. Here, when two archives are extracted, files from second are outside of wrksrc, so they aren't cleaned. This can be fixed by setting `create_wrksrc=yes` and following post-extract, so all files are extracted into wrksrc, then files from first tarball are moved one dir up into expected place. (I missed that second tarball breaks convention of having top-level dir.)
```
post_extract() {
	mv "ccl-${version}"/* .
}

```
