Thanks for the quick reply.

Well, my emacs was already built with gtk3. I wanted to try xwidget
browser out just now, but found no corresponding USE flag.

Corresponding line in package.use:
app-editors/emacs xft imagemagick libxml2 gtk3 xwidgets

Still not working.

BTW I got:
~ $ euse -i -l xwidgets
local use flags (searching: xwidgets)

It seems strange...euse tells me there is a xwidgets USE for emacs, but
equery says something different.

Weird...
