inplace is shadowed by package

I have a library, persistent, that builds. When I try to build the test suite, I get:

Preprocessing library persistent-0.4.0.1...
Preprocessing test suites for persistent-0.4.0.1...
Building persistent-0.4.0.1...
Registering persistent-0.4.0.1...
<command line>: cannot satisfy -package-id persistent-0.4.0.1-inplace:
    persistent-0.4.0.1-inplace is shadowed by package persistent-0.4.0.1-f5ffa1e952f5d8b58608c8d1f9f69825
    (use -v for more information)

The test-suite build-depends has:

                   persistent >= 0.4.0.1,
                   persistent-mongoDB,
                   persistent-postgresql,
                   persistent-sqlite,

persistent-mongoDB (and postgresql and sqlite) depends on persistent to build.

I have tried this twice now from a fairly clean install- immediately after upgrading to a new version of ghc.

Can you tell us what ghc version you're using? Is it 6.12.1?

Can you point us to a concrete example so we can reproduce it?

I received the same result on 6 (6.12 I presume), 7.01 and 7.02

github.com:gregwebs/persistent.git
branch mongoDB5

To attempt to run the tests you will need to install persistent, then cd to the backends directory and cabal install for sqlite,postgresql, and MongoDB, then come back to root persistent directory and try to run the tests.

I created an account in the hopes that commenting here will give me email updates for this issue. Here is the proper cloning url: http://github.com/gregwebs/persistent.git

I am using cabal compiled from HEAD less than a month ago.

Have you had a chance to reproduce? Is there any more information I can provide you with?

I've just had this issue with the attoparsec benchmark:

Any idea what is going on?

I caught this issue after compiling some packages with ghc-7.6.* and another with ghc-7.8.*. Silly me.
But the issue was even with --force-reinstalls option so aren't this packages supposed to be recompiled?

Here's a newer description of what seems to be the problem (regarding test-suites and cyclic dependencies) that helps clear up the key issues involved: http://stackissue.com/tibbe/hashable/higher-kinded-classes-124.html

So this seems to be an instance of #1575

which has an unmerged (stalled?) pr that gives a solution at #3422

Closing in favour of #1575.
