pass for backend

Hi there,

I wrote a pass for my (language)backend, but llc can't load it. I get the following error message:

Hi again,

in fact I get the error message just by adding
#include "llvm/Analysis/PostDominators.h"
to the backend.
And I have no clue why.

PS: I'm using llvm 2.2 and Mac OS X 10.5.3
