Very basic clarification regarding USE flags for emerge


I'm trying to install python with the sqlite use flag. I entered python/ sqlite in the /etc/portage/package.use and then entered emerge -pv python. This is what I got:

Code:
These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] dev-lang/python-2.6.4  USE="berkdb gdbm ipv6 ncurses readline ssl threads (wide-unicode) xml -build -doc -examples -sqlite -tk -wininst" 10,760 kB

Total: 1 package (1 reinstall), Size of downloads: 10,760 kB
Why is -sqlite set?

Why does
Code:
#USE=sqlite emerge -pv python
show what I want while
Code:
#USE=sqlite
#emerge -pv python
doesn't work?

You need to enable the use flag in package.use, by default it's disabled.

also, (assuming bash)
Code:
export USE="sqlite"
emerge python
would exhibit the desired behavior.

Code:
dev-lang/python sqlite
in your /etc/portage/package.use should work.
Code:
6510b ~ # echo "dev-lang/python sqlite" >> /etc/portage/package.use
6510b ~ # emerge -av python

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] dev-lang/python-2.6.4  USE="berkdb gdbm ipv6 ncurses readline sqlite* ssl threads (wide-unicode) xml -build -doc -examples -tk -wininst" 0 kB

I made the mistake of omitting dev-lang in dev-lan/python.
Quote:
export USE="sqlite"
emerge python
Your suggestion worked. What's the difference between USE="sqlite" and export USE="sqlite" as long as I execute the former in the shell directly?

Thank you both!

Basically, each command line is its own individual shell script. If you don't export the variable, it isn't added to your environment for that bash session.
