I would only be engaging in slight hyperbole if I said, "Stack changed my
life." :)

FWIW, that's kind of an old Mint.

"Use stack" is one solution but the Haskell Platform is alive and well too.
Your distro has an old version of the HP but the current HP has a recent GHC.

Seeing as nobody has addressed the second question (Does it matter) here, I'll
put my two cents in.
I've only been using haskell for a few months, on Debian Stable, with the GHC
7.6.3 that comes with Debian Stable. In my limited experience, (especially as
regards my learning process), it hasn't much mattered.
(Actually, if anything, occasionally it seemed it wasn't old enough --
sometimes googling an issue would turn up articles referencing GHC 6)
But I'd be interested in hearing other opinions.
P.S. As a Debian user/enthusiast, I haven't seen any need for bothering with
Platform or Stack--dpkg/apt got everything (I didn't bother with the
"haskell-platform" meta-packages) installed pretty straightforwardly.

Thanks for the hint Peter
