So looking at what is happening, it seems you remove
the dependencies for build-essential packages from
the source packages.  But those don't build-depend
on it in the first place.  You need to change
the Depends on the Packages themself, so
that the files going to edos-debcheck
does not have Depends: perl for debhelper.

I've tried adding a package that provides all the build-essential
packages in 1 package, but that seems to cause problems too.

This has atleast 2 problems:
- Versioned depedencies don't work.  We have things like
  - libtext-format-perl (= 0.52-21) depends on perl (>= 5.6.0-16)
  - autoconf (= 2.64-4) depends on perl (>> 5.005)
  (I've only seen it with perl so far)
- You need to add provides for all the provides the packages
  you try to replace have.  And perl has alot of them.

It might also need to be arch specific, I think hurd has conflicts
with packages that are essential on other arches.

This atleast seems to be giving reasonable results, it might
not be perfect, but would atleast not get us completly stuck.
