It is a mini-repeat of what one had to do to get 7.0 installed.
There were a lot more masked packages to add at that time. I still have
a script I wrote for that purpose, it adds any encountered unstable
ebuilds to the /etc/portage/portage.keywords file and masked ebuilds to /etc/portage/portage.unmask file:

------------------

#!/bin/sh

LASTADD=''
UNMASK=''

if [ -z "$*" ]; then
  echo Need package name to emerge
  exit
fi

until emerge --deep --nocolor --verbose --pretend $* >/tmp/autokw$$; do
  if egrep "All ebuilds that could satisfy \".*\" have been masked." /tmp/autokw$$; then
    #echo error from portage looking at output
    EBUILD=`grep "^- " /tmp/autokw$$ | head -n 1 |\
      sed -e 's/^- \(.*\)-[0-9].*$/\1/'`
    if [ "$EBUILD" == "$LASTADD" -o -z "$EBUILD" ]; then
      echo oops same as last time or null: [$EBUILD]
      if [ ! -z "$UNMASK" ]; then
        echo already tried to unmask package
        rm /tmp/autokw$$
        exit
      fi
      echo trying to add to unmask
      if grep "All ebuilds that could satisfy" /tmp/autokw$$; then
        EBUILD=`grep "All ebuilds that " /tmp/autokw$$ | head -n 1 |\
          sed -e 's/.*"\([^"]*\).*$/\1/'`
        echo $EBUILD >> /etc/portage/package.unmask
        UNMASK="yes"
        LASTADD=''
      fi
    else
      echo adding [$EBUILD] to keywords file
      echo -e "$EBUILD\t~x86" >>/etc/portage/package.keywords;
      LASTADD=$EBUILD
      UNMASK=''
    fi
  else
    echo could not parse output
    cat /tmp/autokw$$
    break
 fi
done
[ -e "/tmp/autokw$$" ] && rm /tmp/autokw$$

It's just a hack but it has worked for me a couple of days ago for 7.2 ebuild. On that note, I have also found the etcportclean script useful (just google for it). It scans your /etc/portage files and tells you if you have any redundant entries there. The script might be broken a little from memory but it has worked quite well for me over a long time.
