Version 1.10 of the xcolor package (dev-tex/xcolor) is out and available at https://sourceforge.net/projects/latex-beamer/ - thanks for updating.
Added to CVS. Thanks for reporting.
esearch xcolor gives the wrong homepage, ie, http://latex-beamer.sourceforge.net/ And here's the (non-sourceforge) homepage (I think. Sorry, n00b here): http://www.ukern.de/tex/xcolor.html
Thanks for the info. I updated xcolor to 1.11 and changed SRC_URI/HOMEPAGE.
