[gentoo-user] Depclean question

I have just used depclean for the first time (I was afraid of it) after
several years of Gentoo. It has cleaned up my system a good bit but now
it wants to remove some packages that I'm concerned about:

gcc-3.4.6-r2 (I'm using 4.1.2)
libstdc++-v3-3.3.4 and virtual/libstdc++
virtual/jdk and virual/jre (it leaves the later versions in both cases)
qt-4.1.4-r2 (leaving qt-3.3.8-r4)
several early versions of db leaving db-4.5.20_p2
and a few others

How much danger is there if I remove these?

Tony

Well, you might find yourself in an un-usable GUI system upon reboot.
To add packages, that you care about, to your world file use: emerge
--noreplace <atom>. Do this with all the packages you want to keep /
you feel are essential to your system.

I'd like, however, that someone more experienced confirm my comments.
Also, look at: http://gentoo-wiki.com/HOWTO_Maintain_Gentoo_-_%22Best_Practices%22#depclean
