Build using two components with a common root directory?

In order to play nicely with a legacy clearcase system, our project needs to ensure that all of our files live under a predefined root directory. We'd like to split the files between multiple components, but our build is failing due to the overlap:

Is there a workaround for this? Our structure is basically:

/component1/commonDir/project1
/component2/commonDir/project2

And I've tried using component load rules to specify something like:

RootFolderName=/commonDir/project1

in the component1 load rules and:

RootFolderName=/commonDir/project2

in the component2 load rules. With these rules, I get the slightly different error:

Wondering if there are other tricks to try or if this is not supported currently.

Thanks very much,
