[gentoo-user] problems with world update and chromium and maybe something else

[covici@ccs.covici.com]

Hi.  So, in my attempt at the recent world update, I would like not to
use  wayland because of accessibility problems and yet I see:

These are the packages that would be merged, in order:

  The following REQUIRED_USE flag constraints are unsatisfied:
    screencast? ( wayland )

  The above constraints are a subset of the following complete expression:

Also, where do I put lvm19 --what is portage looking for?

Thanks in advance for any suggestions.
