Multiple Boost versions on one System?

[Demonking]

Hello,

i wanted to ask, if there is a way to have multiple Boost versions on 1 System.
For my education i need the new Boost 1.53 but for my work i need 1.49.x .
I remember that earlier there were a boost eselect, but it seems to have disappeared?

Anyone an idea?

A workaroung for your use case could be

1. an additional kernel cmdline parameter having started by a special grub selection:
boost_for_work

2. you then could in /etc/local.d/<script>
if grep boost_for_work /proc/cmdline

3. quickly emerge back a suitable set
emerge --ask=n --usepkg @boost_work_set

I keep package bins after compile by heaving in /etc/portage/make.conf:

Slotted Boost was convenient for users, but such a pain for the maintainers that it is no longer supported. You must install at most one version of Boost.

if you are brave you may check if my overlay with slotted boost still works. see my sig.
sadly, I have no time to maintain it anymore.
