RE: [gentoo-dev] virtual problem

[Sean P. Kane]

A note: I found out all I did about virtuals from the Documentation, so
it is in there somewhere. The ebuilds are in constant change, so it is
likely that people are adding virutals, because the app depends on it,
but it wasn't listed in depends earlier. You can always try and edit the
ebuild for yourself and see if you can get it to build. Remove the
depend or something and see if it works. Take a look under
/usr/portage/.

True, this email is the most detail I have found about "virtual" stuff
yet, I cannot find any doco's on this which is why the emails.

It appears to be tied up with the opengl mess - that is most of the
programs are complaining of opengl, glu or glut (by the way this is a 2
month old install that "suddenly" started complaing of this - so whats
changed?  I see that there are some odd comments about Mesa not playing
nicely in the files with nvidia, but I dont have an nvidia card so I'll
unmask and install Mesa and hope that works.  In the meantime, what
about xmms, xscreensaver and a number of others which suddenly will not
build becuase something virtual has poppped up - they have not always
been this way!

I did a fresh install into a vmware VM over the last couple of days and
cannot finish the install as that is now complaining of the same
problems.

Starting to look like something is screwy with the portage tree.
