Is pkgsrc on an ageing/obsolete Linux distro a good idea?

[Ottavio Caruso <ottavio2006-degen%yahoo.com@localhost>]

I fiddled with pkgsrc on Linux a couple of years ago, but I had to
give up because I didn't have much time and I wanted an usable system
to start using right away.

That "usable system" was Linux Mint Debian Edition v2 (Mate) which now
is almost obsolete. I have a few packages that I'd like to install but
they are not being maintained for Debian Jessie.

Rather than making a new clean install with a new distro that might or
might not work with my old-ish Thinkpad, I was thinking of giving
pkgsrc another go.

I was only wondering: at one point I will have obsolete libraries,
kernel modules, firmware, etc. Would that give any trouble to the
pkgsrc subsystem on my installation?

Thanks
