As far as I understand the problem is only a problem with an older
version of Cabal and cabal-install. Is there a reason why you can't
update your Cabal to a current version? I still do not feel encouraged
to downgrade my package (and others with the Tested-With field).
Alternatively you may modify the package privately and install it as
say, data-accessor-0.2.1.3.1.
I have upgraded to cabal install 0.8 to solve this problem. However,
many people still use 0.6, and it is included in distro's as well.
Additionally, the problem doesn't only occur when trying to install
data-accessor, but also when installing something else that has
data-accessor in its dependency tree anywhere, even if cabal-install
finally decides it doesn't even need to install data-accessor (as it
did in my case). This means even if you have data-accessor installed
already, packages that depend on it (or depend on packages that depend
on it, etc) fail to install.
It did already annoy me a lot, that cabal-install cannot just accept even
successfully installed packages. But I think this is a problem of
cabal-install not of data-accessor and other packages that use the
Tested-With field.
