Subject: GHC <at> 8.6.5 can't find errno.h
Date: Tue, 1 Dec 2020 10:54:55 +0100

Haven't had a chance to try with latest version, because there is no
substitute yet.
It's a very basic Haskell file, only imports are Data.List and
System.IO. GHCI works.

I'm pretty sure I didn't need to add any other packages to my profile
when I last used GHC, but maybe things have changed since then or I'm
misremembering, or I usde to have just the right assortment of packages.

Nevermind, my expectations for the profile's /etc/profile were
incorrect. Looks like I don't have to re-source it for new commands,
but I do for... well, whatever kind of dependency this was.
