*DON'T* do that. It appears that "emerge --pretend --prune" blindly
tells you to delete all but one version of a package. That can be a
*BAAAAD* idea. Here is part of its output on my system...
x11-libs/gtk+
selected: 1.2.10-r11
protected: 2.6.10-r1
omitted: none
sys-devel/automake
selected: 1.5 1.6.3 1.7.9-r1 1.4_p6 1.8.5-r3
protected: 1.9.6-r1
omitted: none
sys-devel/autoconf
selected: 2.13
protected: 2.59-r6
omitted: none
But "emerge --pretend --emptytree xmms" on my system wants (amongst
other things)...
[ebuild N ] sys-devel/autoconf- 2.13
[ebuild N ] sys-devel/autoconf-2.59-r6
[ebuild N ] sys-devel/automake-1.5
[ebuild N ] sys-devel/automake-1.8.5-r3
[ebuild N ] sys-devel/automake-1.6.3
[ebuild N ] sys-devel/automake- 1.7.9-r1
[ebuild N ] sys-devel/automake-1.4_p6
[ebuild N ] sys-devel/automake-wrapper-1-r1
[ebuild N ] sys-devel/automake-1.9.6-r1
[ebuild N ] x11-libs/gtk+-1.2.10-r11
That's just 1 app. I'm sure there are others that would experience
similar breakage. If you "emerge --pretend --emptytree --world" and an
old version listed for deletion by --prune does *NOT* show up, you'll
probably be safe removing it. Maybe "emerge --pretend --prune" needs to
run "emerge --pretend --emptytree --world" by default, and use its
output as a sanity-check before recommending deletions.
