Hi all,

Libreoffice-4.0 needs boost > 1.49 (so works with boost-1.52.0-r5) and
Nightshade LSS (for planetarium but not in portage) needs boost < 1.5
(so works with 1.49.0-r2).
Is it possible to install both 1.49 and 1.52 (in new slot) ?

No.

Boost IIRC used to be slotted, but not anymore. Like any other package,
you get one and only one version at a time.

When i emerge boost-1.52, boots-1.49 in uninstalled and vice versa.

So don't install boost-1.52 and take it out of world if you have it
there.

Portage will install boost-1.49.0-r2 for you and maintain the updates
for you. You do not have to fiddle with it.

What if I need boost-1.52 for my own software I build?
