files were dropped (mostly entry_points.txt) or .egg-info files changed
to directories. Small patches were needed where some other build systems
were calling Python tools to install due to changes in setuptools.
Messy patching needed for games/0ad which bundles a spidermonkey tar of
a specific version and patches it using files in its own distribution.
Been through a bulk on i386, plus I tested a few things separately on
amd64 where fallout from the recent qscintilla update has broken some ports
on !LP64 which was blocking them on i386.
