This won't work. An atom with a version prefix must have a version number.

You are looking in the wrong place. I would suggest that you first read all 
the portage man pages:

man emerge
man 5 make.conf
man 5 portage
man 5 ebuild

It's a lot of stuff but it's all necessary.

Now look at your original error and see what is there instead of what you 
think might be there. It clearly says that the package is hard masked, and 
that it is package.mask that is doing it. If you look in that file, you see:

nazgul ~ # grep spca /var/portage/profiles/package.mask
# Sorting out media-video/{spca5xx,gspca{,v1}} bug 159176
media-video/spca5xx
media-video/gspca

You can fiddle with package.keywords for the next century, it won't make a 
difference. You need to unmask these packages with entries 
in /etc/portage/package.unmask
