dpkg-checkbuilddeps supports Provides correctly, the problem here is
that it does not support versioned Provides (as is the case for the
whole package managment stack). So I suppose sbuild should fail
sooner, and all those perl packages should be fixed to update their
Build-Dependencies (given that perl-modules is Build-Essential, just
removing the offending packages which are provided by it should be
enough).
