Nix (https://nixos.org) is a Unix package manager, which can be used to
install LaTeX on macOS. A peculiarity of Nix is that all packages are
installed into separate directories and the actual directory tree is
then constructed via symlinks.
This interacts badly with the way LyX currently detects files in the
TeX setup, because TeXFiles.py does not follow symlinks. Therefore,
almost nothing is found when using LyX together with Nix’ LaTeX.
Patch from Michael Roitzsch.
Fedora ships these chmod 644 and has never seen a problem. The advantage
to doing this is that it better controls what version of python we are
using to launch the script, and it will reveal if we're somehow somewhere
not controlling that properly.
On Cygwin, the most reliable way to tell what is the right path
separator to use is a direct check.
