Not comfortable with the install?  Are our docs outdated or ambiguous?

No problem so far.

Is the goal to test out an unkeyworded ebuild for keywording/porting? 
This looks like a good way to go for that purpose.

Indeed, mine is a ~ppc-macos portage system.

What is the bug, exactly?  If they're trying to run an ~arch package on 
an arch system, this is how you do it.  There will likely be 
dependencies to also be pulled from ~arch, but portage handles that AFAIK.

Portage should handle this.  As I understand it, portage doesn't care 
too much about arch/~arch.  The KEYWORD just sets up some default 
packages masks, if you will, from which it can draw from known packages 
and their dependencies.  When you get down to installing a package 
(regardless of keyword), portage makes sure the system and ebuild 
keywords match and then it starts building the dependency tree.  The 
same checks must be made for each dep.  If it was called something like 
# ACCEPT_KEYWORDS="~arch" emerge foo/bar then for that run or portage, 
the system _is_ an ~arch system, meaning all deps will be pulled from 
~arch.  I'm not sure how it handles entries in the package.keywords 
file.  The behavior may be different; feel free to chime in, anyone who 

Be careful about your terms here.  We currently have a use for the term 
"progressive".  I believe I understand what you're saying about 
controlled risk; don't know if it would confuse anyone else.

I'm afraid I don't understand what (if anything) needs to be done.  Care 
to elaborate?
