Set backup MANPATH in case man path isn’t set correctly.
Previously, this would fail at startup for non-NixOS installs: nix-env --help The fix for this is to just use "nixManDir" as the value for MANPATH when spawning "man". To test this, I’m using the following: $ nix-build release.nix -A build $ MANPATH= ./result/bin/nix-env --help Fixes #1627
