Well, I've read about that before and am using the default bdep
behavior but I guess I don't understand it entirely.

I've isolated basically all of the new/changed packages down to
openoffice-3.0.0 -- if I do "emerge -vtp openoffice" it shows me this:

[ebuild   R   ] app-office/openoffice-3.0.0  USE="binfilter cups dbus
gtk java kde ldap mono nsplugin opengl pam -debug -eds -gnome
-gstreamer -odk -templates" LINGUAS="en en_US -af -ar -as_IN -be_BY
-bg -bn -br -bs -ca -cs -cy -da -de -dz -el -en_GB -en_ZA -eo -es -et
-fa -fi -fr -ga -gl -gu_IN -he -hi_IN -hr -hu -it -ja -km -ko -ku -lt

-th -ti_ER -tn -tr -ts -uk -ur_IN -ve -vi -xh -zh_CN -zh_TW -zu"
10,552 kB

So, apparently openoffice has ~10 megabytes of unfetched files even
though I have not deleted any openoffice distfiles since I emerged it
in November. That would make me think maybe the ebuild has changed
without a version number change. Checking the date on the ebuild it is
January 11 2009.  However, the date on
/var/db/pkg/app-office/openoffice-3.0.0/openoffice-3.0.0.ebuild is
November 3 2008. A diff of the files shows some material changes
(downloading newer builds from go-oo.org etc). So in this particular
case I think my suspicion about the ebuild changing without a version
number revision might be right.

When I do "emerge -Dtp openoffice" it shows this:

Calculating dependencies ... done!

I'm still not entirely clear on why those appear with --deep
openoffice but not --deep world. If they are build-time deps, wouldn't
they be included when I emerge openofifce without --deep? If they are
related to dev-perl/Archive-Zip-1.26 (as it appears), which is
installed, why don't they get touched by @world? Maybe I just can't
wrap my brain around how it works, please have patience with me.
thanks :)
