I think we could leave out the <cmd/> element here.

Sounds quite good. Additionally, we should make the configure and build
stages optional since they're not needed for (most) binaries.

For DPKG (or DEB?) this would just be:

  <stages>
    <install scheme="DPKG"/>
  </stages>

  <!-- Pre-defined DPKG scheme implemented in InstallIt: -->
  <action stage="install" scheme="DPKG">
    dpkg --install ${FILE}
  </action>

Substitutions like ${GNUMAKE}, ${BSDINSTALL}, ${PREFIX} and ${FILE}
would be provided by InstallIt, then. Right?
