Can't start review shell with multiple qt versions

[SuperSandro2000]

When a review shell contains multiple version of libsForQt5 it just closes with an error:

$ nixpkgs-review pr 115224

1 package failed to build:
libsForQt512.ark

3 packages built:
libsForQt5.ark libsForQt514.ark lrzip

Is this caused by shell hooks?

[SuperSandro2000]

I don't think so. I think the problem is that the buildenv is combining multiple qt versions which is not allowed.

[Mic92]

buildenv should be not used for 4 packages.

[SuperSandro2000]

Apparently it does not matter if buildenv is used.

I encountered this when testing NixOS/nixpkgs#368474 via nixpkgs-review rev fix/partition-manager-drop-reiserfs.
It affects two partitionmanager drvs, with Qt 5 and Qt 6.
