According to DOCS/xml/README in mplayer dist there is no need of app-text/docbook-sgml-dtd and app-text/docbook-xml-simple-dtd deps.
Have you *verified* that it works without those?
Yes, I have. I copy mplayer-1.0_rc2_pre20070321-r4.ebuild to local overlay, changed it like this: DEPEND="${RDEPEND} app-arch/unzip doc? ( app-text/docbook-xml-dtd dev-libs/libxslt ) and recompile mplayer. It works!
BTW, do we need any of this .svn dirs in /usr/share/doc/mplayer-1.0_rc2_pre20070321-r4/{DOCS,TOOLS}/ and below?
And, of course, I emerge --unmerge docbook-sgml-dtd docbook-xml-simple-dtd before merging mplayer
Fixed in mplayer-1.0_rc2_p28058
Thanks a lot!
