Well, sci-mathematics/singular is in world, but singular-3.1.3 satisfies
this dependency so it should be no problem.  To me this looks like a
portage quirk.  Also note that I don't get these messages without the -D
option of portage (but it also does not pick up possible upgrades in
this case.)  

OK, I just tried removing singular and maxima from the world file and
then it works.  It still shows the two messages for numpy and pexpect,
they are just not fatal anymore.

I don't see through...
Cheers,
Thomas
