Try using a JIT-style python compiler.
#nano -w `which emerge`
Add the bit from try: to pass in like so:
sys.path = ["/usr/lib/portage/pym"]+sys.path
use tabs for the indented bits. you can also try the experimental
database support (I'm using it, seems fine)
# mkdir /etc/portage
# echo 'portdbapi.auxdbmodule="portage_db_anydbm.database"' > /etc/portage/modules
# echo 'eclass_cache.dbmodule="portage_db_anydbm.database"' >> /etc/portage/modules
Both of these speed up portage quite a bit...
