Bug#695076: pbuilder-satisfydepends-classic: does not honour versioning in Build-Conflicts

[Thorsten Glaser]

Package: pbuilder
Version: 0.213
Severity: important

I try to build: kde4libs_4.8.4-4.dsc

It has:
Build-Depends: […], libqtwebkit-dev, […]
Build-Conflicts: libqtwebkit-dev (<< 2.2.1)

Then pbuilder-satisfydepends-classic installs libqtwebkit-dev:

Then it removes it, despite definitely *not* being << 2.2.1 !
