Setting those vars shouldn't be *required*. Try to follow steps in
HACKING.md (i.e. compile a Setup script manually and run './Setup
[configure --enable tests | build | test]').

It should look approx. like this:
'CABAL_PACKAGETESTS_DB_STACK=clear:global:/path/to/.cabal-sandbox/x86_64-linux-ghc-7.8.4-packages.conf.d'.
This assumes that you installed the version of Cabal you're testing
into a sandbox under '/path/to/.cabal-sandbox'.
