Bugzilla Bug 143511

Library libXaw3d.so.7 is required by Scilab 2.7-r3, but this library is not
built during "emerge scilab" and is not available. Maybe scilab should be
linked to libXaw3d.so.8.0 from x11-libs/Xaw3d-1.5-r1 instead?

Erm, does revdep-rebuild fix the problem?

Every run of revdep-rebuild tries again to resolve the missing dependency on
libXaw3d.so.7 by re-emerging scilab, but the problem persists.
