[gentoo-user] graphviz won't compile

[Alain Didierjean]

Cannot emerge graphviz :

 ERROR: media-gfx/graphviz-2.26.3-r4::gentoo failed (prepare phase):
 *   (no error message)
 * 
 * Call stack:
 *     ebuild.sh, line  93:  Called src_prepare
 *   environment, line 5657:  Called die
 * The specific snippet of code:
 *           cp "${EPREFIX}"/usr/share/libtool/config/install-sh config || die;

libtool ebuild doesn't install /usr/share/ligtool/config directory.

Known bug, or should I report it ?
Thx
