xbmc git supports optionally building the bundled Really Slick XScreenSavers (rsxs) package. I have no need for rsxs since I only use the inbuilt dim screensaver.
Would be very nice to be able to disable this option by USE flag, I agree 100%
should be all set now in the tree; thanks for the report! Commit message: Make slick screensavers optional http://sources.gentoo.org/media-tv/xbmc/metadata.xml?r1=1.7&r2=1.8 http://sources.gentoo.org/media-tv/xbmc/xbmc-9999.ebuild?r1=1.87&r2=1.88
