Cabal not installing dependencies when needing profiling libraries?

Here is the situation. I want to install\reinstall package A with some new options or flags (for example I've add library-profiling: True in ~/.cabal/config). 

cabal install --reinstall A

Package A depends on package B, which installed without support that options. That why (if I'm understanding that correctly) tells me that:

Could not find module `B':
  Perhaps you haven't installed the profiling libraries for package `B'?
  Use -v to see a list of the files searched for.

So I need to reinstall package B and then try to install package A:

cabal install --reinstall B
cabal install --reinstall A

All I want is to tell cabal that I need to reinstall all packages that depends on A automatically. How can I do that?

    I suggest we reopen this question. The cited dup is over a year old and since then we, as a community, have developed the cab and cabal-dev tools which offer better solutions. – Thomas M. DuBuisson Dec 10 '11 at 22:58
