This happens because upstream of benchmark-ips removed
benchmark/helpers; see here[1].
For the very same, I'm attaching the patch to fix this :)

Furthermore, I've pushed the fix and the changes to the salsa repo,
which could be found here[2].
NOTE: Since there's no gemspec present (either in debian or
upstream[3]), I've left it as is. This also means the autopkgtest would
*not* be able to parse the dependencies and wouldn't proceed.
I'll leave that to you and for the maintainer of this package to decide :)

That said, ruby-benchmark-suite *now* works with ruby-benchmark-ips 2.7
in experimental.


Best,
Utkarsh
