Yes! Using

     ./raco pkg install --scope installation poppler-i386-macosx

from the command line worked. And later I saw that the GUI also
allows one to choose installation scope in settings.

This problem is luckily restricted to a fairly small set of libraries.

I have yet to test on Windows.

Thanks for the help,
