Is it possible to show a specific error message when running in a
circular dependency?

When I get it right, the problem occurs only one time when solved
with a bundled use flag. As soon as expat and/or cmake are installed,
follow up versions can be merge without problems.

If an error message can be shown, maybe this is enough as a hint:
"expat and cmake have circular dependencies. Emerge it the first time with:
USE=bundled-cmake emerge -1 cmake expat
and then just don't care anymore about this use flag."

Of course, the same applies for other known circular dependencies, too.
At least for me as a user, this would be enough.
