[DRE-maint] Bug#632776: Bug#632776: ruby-shoulda-context, gem2deb: Circular build-dependency

[Lucas Nussbaum]

Hi,

I don't think that we should "fix" that problem by dropping
build-dependencies. 

The fact that gem2deb is being extensively tested at build time is a
very nice feature, and we should not break that.

However, just for reference, we should probably document that it's
possible to build gem2deb with a minimal set of build-dependencies if
one disable the tests.
