The configure script fails if dts is not set in USE: """ Unknown parameter: --disable-libdts !!! ERROR: media-video/mplayer-1.0.20070622 failed. Call stack: ebuild.sh, line 1569: Called dyn_compile ebuild.sh, line 938: Called src_compile mplayer-1.0.20070622.ebuild, line 422: Called die """ Removing the offending line from the ebuild fixes this: use dts || myconf="${myconf} --disable-libdts"
fixed in CVS, thanks for the bug report
