Gopass setup using age seems to fail on pinentry request

[AnomalRoil]

Steps To Reproduce

git clone 
cd gopass
go build
./gopass setup --crypto age

Expected behavior

I would have expected it to work out of the box.

Thoughts

Could this be related to #2095 ??

Actually this seems to be the same issue as here: #1879

Did you try installing / using pinentry-mac?

Solved by exporting export GPG_TTY=$(tty) on my side.
