[gentoo-dev] db questions

I recently noticed I have 5 versions of db installed now (~x86), and my 
question is this: since qpkg is lying to me and says I need them all and the 
ebuilds say different, what versions are actually required now, and is there 
any chance that we'll get to just one in the future?:)

It's highly unlikely that we will get the point where we will need only
one.

I don't know where you get five versions however, this is what most
machines will end up with over time (these are also the 4 slots):
sys-libs/db-1*
sys-libs/db-3*
sys-libs/db-4.0*
sys-libs/db-4.1*

The reasoning behind this is repeated API changes have lead programs to
specificly link against some version, or come up with fancy macros
(which break often) to try and work with lots of them.

The major problem with the API changes is changes in the order and
number of parameters of some function calls.

There are programs in portage that specificly look for all of
those slotted variants.

I was mistaken, there are only four installed. I was somewhat aware of the 
why, but my concern lay in qpkg's lies:
# qpkg -q -I -nc db
sys-libs/db-3.2.9-r6
DEPENDED ON BY:
        perl-5.8.1-r2
        python-2.2.3-r3
        postfix-2.0.16-r1
        libperl-5.8.1
sys-libs/db-1.85-r1
DEPENDED ON BY:
        perl-5.8.1-r2
        python-2.2.3-r3
        postfix-2.0.16-r1
        libperl-5.8.1
sys-libs/db-4.0.14-r2
DEPENDED ON BY:
        perl-5.8.1-r2
        python-2.2.3-r3
        postfix-2.0.16-r1
        libperl-5.8.1
sys-libs/db-4.1.25_p1-r2
DEPENDED ON BY:
        perl-5.8.1-r2
        python-2.2.3-r3
        postfix-2.0.16-r1
        libperl-5.8.1

IIRC, these four, which represents the sum of stuff I have linked to db, call 
for db3 in the ebuilds. I dont mind testing the new, if something I used 
linked to it, and I am used to seeing at least the two copies that have been 
haunting for awhile(db1.85 and db3), but would it be possible to find out 
truthfully what is actually linked and to unmerge/mask/crucify the others?

Yeah, that's the most current of the lot.
Try 'emerge -epD world' and pipe that to a file, then see which versions
of db-3
