homebrew build-from-source post-install step issue with homebrew-freecad-bundle.pth check

[nachumk]

When installing FreeCAD from source, the post-install step fails because of this check:
if !File.exist?("/usr/local/Cellar/freecad/0.19pre/lib/python3.9/site-packages/homebrew-freecad-bundle.pth")
(lib/"python3.9/site-packages/homebrew-freecad-bundle.pth").write "#{prefix}/MacOS/\n"
end

Since it is built from HEAD, the folder name should be:
/usr/local/Cellar/freecad/HEAD-6b3936c
and not
/usr/local/Cellar/freecad/0.19pre

The verbose output shows:
/usr/local/Homebrew/Library/Homebrew/brew.rb (Formulary::TapLoader): loading /usr/local/Homebrew/Library/Taps/freecad/homebrew-freecad/Formula/freecad.rb

I will be fixing that issue shortly as soon as we can close the macapp creation issue.

closing this issue as this is no longer relevant with current install of freecad with the current formula file defined within this repo.
