Please, attach unified diffs next time, much easier to review...
Adressed in 0.2.4-r1; 0.2.3 is now marked stable and off-limits for changes that would require a rebuild.
Update: There will be no 0.2.4 ebuild as this release has been pulled. Reopening bug.
Addressed in release 1.0.0; thanks for your bug report. As Jacub suggested, a unified diff would be appreciated next time.
