install is failing on OSX 10.13.6

with

stack --version
Version 1.9.3, Git revision 40cf7b37526b86d1676da82167ea8758a854953b (6211 commits) x86_64 hpack-0.31.1

ghci --version
The Glorious Glasgow Haskell Compilation System, version 8.6.3

Anybody have a hint on how I can fix this ?

What stack resolver are you using? I just tried and it installed fine on lts-13.10.

If you are trying to install this globally, the entire contents of ~/.stack/global-project/stack.yaml would be useful to see (secrets removed if any are present of course)
