I had a little correspondence with thp.
I understood why he had removed the binaries from the site.
For this reason, the available apkenv-qml packages don't contain them.
I think it would be ethical to remove any posted packages/binaries.
To work correctly, you need to place all the apkenv binaries in "/opt/apkenv/bin" with rights to execute.
I'm planing to add path setting in apkenv-qml in future.
