No, that's not what I'm trying to do. I had introduced a patch that
ran tests for target packages and aborted installation if the tests
failed. For example,

> cabal install --enable-tests network

would install all network's dependencies (but not their tests), then
build, test, and install network. It didn't change how dependencies
were handled at all. However, the test runner in Cabal wasn't designed
to be invoked from cabal-install: it sometimes exits on success, which
cabal-install interprets as an error, even when it isn't. This was
stopping packages without tests from being installed with 'cabal
install --enable-tests', which shouldn't happen.
