You should never do things like:
USE="some_flags" emerge some_package
Instead you should configure a set of useflags you think are good for
your needs in general in make.conf. If you want to overide these
settings for a specific package do so by using /etc/portage/package.use.
Just to give you an example, my make.conf contains this:
USE="3dnow alsa bzlib gphoto2 apm jpeg mmx xine xmms zlib opengl
oggvorbis gnome gtk gtk2
sse 3dnowext sqlite usb -emacs -flac -php -pyton -mysql -matrox
-kde -wxwindows -scanner -samba -yahoo -oci
-qt unicode evo mmxext dvdr -eds hal dbus firefox nvidia dvd
win32codecs
-firebird nsplugin -arts real flac theora vcd css -oss nautilus
cairo a52 avi dvdread divx4linux dv encode fame mpeg ogg
quicktime subtitles vorbis xvid nptl wma
-apache -apache2 fam -esd"
You find documentation on the various gentoo use flags at:
http://www.gentoo.org/dyn/use-index.xml
For example, to emerge dev-libs/boost with "+debug +doc +threads" on my
system, i did:
# echo "dev-libs/boost debug doc threads" >> /etc/portage/package.use
# emerge -av boost
By the why, if you think "emerge -s some_package" is slow, then
# emerge eix
This is a really nice tool for searching trough portage fast and with
very nice and informative output. Instead of
# emerge sync
you can do
# eix-sync
