Comment 7 for bug 121220

Bochs has docbook-utils in the build-dependencies which depends on docbook-dsssl. This depends on docbook. apt-get build-dep bochs in a clean chroot installs these three packages.
It builds fine in the same chroot without installing any other packages (no xorg-dev either). Therefore, i'll mark it as invalid. Reopen if you can give additional information on the xorg-dev dependency.
