Andrey Grozin, in maxima-5.35.1.ebuild:104 you have included wish-1 patch, though wish-1.patch is missed in the files/ directory.
Same problem here, fails to emerge with >>> Source unpacked in /var/tmp/portage/sci-mathematics/maxima-5.35.1/work >>> Preparing source in /var/tmp/portage/sci-mathematics/maxima-5.35.1/work/maxima-5.35.1 ... * Applying xdg-utils-0.patch ... [ ok ] * Cannot find $EPATCH_SOURCE! Value for $EPATCH_SOURCE is: * * /usr/portage/sci-mathematics/maxima/files/wish-1.patch * ( wish-1.patch ) * ERROR: sci-mathematics/maxima-5.35.1::gentoo failed (prepare phase): * Cannot find $EPATCH_SOURCE! * * Call stack: * ebuild.sh, line 93: Called src_prepare * environment, line 2857: Called epatch '/usr/portage/sci-mathematics/maxima/files/wish-1.patch' * environment, line 1449: Called die * The specific snippet of code: * die "Cannot find \$EPATCH_SOURCE!";
Forgot to cvs add, sorry 22 Dec 2014; Andrey Grozin <grozin@gentoo.org> +files/wish-1.patch: Adding a missing patch (#533202)
Thanks this now emerged for me.
