pstoedit test is failing

[apjanke]

The pstoedit test is failing, both on my local 10.9.5 box, and in the CI when pulled in for the freetype formula (#44587).

Looks like it's calling ghostscript's gs from the wrong location.

sh: /usr/local/opt/ghostscript/bin/gs: No such file or directory
...
$ ls /usr/local/opt/ghostscript
gls: cannot access '/usr/local/opt/ghostscript': No such file or directory
$ which gs
/usr/local/bin/gs

I think this is because the ghostscript installation on my machine was messed up. The /usr/local/opt/ghostscript directory didn't exist, and when I tried to reinstall ghostscript, I got a link error.

already exists. You may want to remove it:
  rm '/usr/local/bin/dvipdf'

To force the link and overwrite all conflicting files:
  brew link --overwrite ghostscript

To list all files that would be deleted:
  brew link --overwrite --dry-run ghostscript

Possible conflicting files are:
/usr/local/bin/dvipdf
/usr/local/bin/eps2eps
/usr/local/bin/font2c
/usr/local/bin/gs -> /usr/local/bin/gs-X11

On the freetype tests, it looks like ghostscript is being uninstalled before the pstoedit test is run for the second time.

Nevermind, mostly. My local failure was due to a non-brewed ghostscript breaking the ghostscript link step, so the dependency was broken.

Might indicate an issue with the brew dependency logic. The failed link step for ghostscript did not abort the installation of pstoedit, and even though brew install exited nonzero, there was no error message visible on the screen because diagnostic info had scrolled the error off the terminal window, and the "successful install" 🍺 beer emoji was displayed. I didn't even notice the installation had failed. If it wasn't for the fact that I have an exit status indicator in my custom shell prompt,

I have the same issue. Did you figure out a solution, perhaps?
Edit: solution.

sudo rm -rf /usr/local/share/ghostscript/
brew link --overwrite ghostscript

[apjanke]

Sounds good. Probably don't need to modify the formula for that since it's a conflict with software installed by other means and should show up under brew doctor.

Thanks!
