No, not really, at least for me. I've got multiple problems here:

1) Evolution crashes

2) emerge --depclean wants to remove things that seem to be
dependencies for installed programs

3) While building things to get up to date I get all these libtool
warning messages which I started to think might be somehow the root
cause of #1 or #2 above.

I'd like to fix all three and to Bo's credit he's doing everything he
can to help a poor old user type like me.

No. The machine is 4 years old. It ran fluxbox for about a year and
then has run Gnome ever since. Evolution has been used in both
environments and worked perfectly until moving from Gnome-2.14 to 2.16
a week or so ago. The gcc-4.1 upgrade was done at Christmas and
Gnome-2.14 and Evolution-2.4 worked fine after that upgrade but not
now. I'm currently looking for the root cause if these crashes.

Not being a developer the first thing I thought to do was look to see
if all the dependencies were clean so basically I did:

eix-sync
emerge -pvDuN world
revdep-rebuild

until everything looked good. I then look a look at emerge --depclean
and saw that there were about 60 packages that it wanted to remove. I
worked my way through each and every one doing an equery depends,
removing it if there were no dependencies, and then every so often
running revdep-rebuild again. However what I started finding as I got
to the end of the process was that out of the 60 packages ot be
removed 15 showed that something at the application level - Gnome,
Evolution, spamassasin, etc., that needed something that --depclean
wanted to remove.

For kicked I did an emerge -C on one package and then immediately did
a revdep-rebuild. The system emerged what I just removed. That's when
I contacted the list.

Based on my response above should I be doing this? From the info I
posted earlier if I emerge -C jasper, as --depclean wants to do, then
it seems it will just be emerged again at emerge -DuN world.

I'm happy to do it if it's the right thing to do. I'm just not
understanding why it should fix things.


Thanks much,
