Not at the moment, sorry.

Unlike native package managers, cabal-install only uses the information
from ghc-pkg. Unfortunately profiling libs are not tracked separately
from ordinary ones so we simply do not know if they are installed or
not. The plan for ghc-6.12 is to track each "way" that a package is
built separately.

It's not impossible that we could hack things for the special case of
profiling libs within the current scheme. (It would involve probing lots
of disk files.) It is however a task amongst many. It would need a
volunteer or it's not likely to get done soon.
