Comment (by simonpj):

 Simon Marlow's response is this: "Compile your program with `-prof`, run
 with `+RTS -xc`" and you'll get exactly the backtrace you want".

 You have to compile a profiled version of the packages you install, but
 you can do that by adding `--enable-pofiling` to Cabal, and you can put
 that in your `~/.cabal` file.

 Doesn't that do it?

 Simon
