Compiling www/chromium on rpi3

[bob prohaska]

After considerable time www/chromium compiled with -DBATCH on an RPI3 
running r362742.  More's the wonder, it actually works....well, mostly. 
Clicking on the rightmost "controls" menu item (three dots) drops the box 
for the menu, but it never fills and disapears immediately. There are lots
of warnings and messages on the controlling terminal:

Both hald and dbus are enabled. Is there some other service to be turned on?

If a session is opened across the network a browser window opens but remains
blank, at least on rapsiOS. At that point it seems stuck, but responds to
control-C on the controlling terminal to kill it.

Compliments and thanks to the many folks who made this exercise work at all!

Thanks for reading,
