#reinstall portage itself to ensure lasest version is installed
emerge portage

#same for autoconf/make
emerge autoconf automake

#this unbreaks some stuff
emerge pam

#update config files
etc-update

for those who like gui, once portage is installed you could do
webportage http://sourceforge.net/projects/webportage/ a webmin type
interface for portage.
