Hi Dale,

thanks for the info and help!

Just a few seconds before I found the reason for all that reasons :)

It seems that -- exactly as you said -- this option prevents
reemergeing of the same packages again.

If you want to force an update "gnu/foobar" (for example) you need to
submit

    emerge --selective=n gnu/foobar

which temporarily overwrites --changed-deps.

By the way: I appreciate helps like yours much more than just pointing
to the obvious docs. ;)

Cheers!
