Comment:
```suggestion
distfiles="https://archive.apache.org/dist/httpd/httpd-${version}.tar.bz2"
```
I don't know if it's appropriate for this package, but `https://archive.apache.org/dist` does not delete outdated versions which would help for local testing when revbumping (as the distfiles are not cached locally if they have not been used earlier).
