When I try to emerge qwtplot3d I get the following error message:

I guess it's a missing dependendy. I've been trying to check what's missing, 
but I haven't been successfull yet. 
 

I resolved this issue by running 
opengl-update xorg-x11 
as my open-gl installation was broken. Apparently this wasn't checked before, 
so it might be useful to add a check for a sane opengl installation. 
Unfortunately I'm not able to do this (cause I don't know how). 

(In reply to comment #6)

You're quite right.  Unfortunately I don't know how to do this either (I assume 
it's some kind of virtual, but can't find where these are documented). 

need version bump to 0.2.5.

I built 0.2.5 successfully by changing this ebuild's name and switching the
QWTPVER variable to 0.2.5 in the ebuild.

x11-libs/qwtplot3d-0.2.6 added to CVS. I cleaned up a few bits and made it 
multilib friendly - looks good here.
