Sorry, I've been slow in replying.

I tend to be a bit reluctant to expose more internal functions to Setup
scripts. It means there's more stuff we can't change without breaking
packages.

In this case I'm not convinced you need it, running your Setup.hs I get
duplicate reports for the programs in question because configure already
reports them. The extra warnings are fine of course.

$ runghc Setup.hs configure -v
Configuring PER-0.0.20...

The last three lines are the bits produced by the Setup.hs and the
earlier bits are from the normal configure.
