build failure on macOS using homebrew

[Ben Abbott]

I’m seeing the failure below. I haven’t built in a week or so.

make[2]: *** No rule to make target `-L/usr/local/opt/freetype/lib', needed by 
`libinterp/dldfcn/__delaunayn__.la'.  Stop.

I’m using hombrew which uses sym-links to a non-stardard location.

ls -l /usr/local/opt/freetype
lrwxr-xr-x  1 bpabbott  admin  24 May  6 14:05 /usr/local/opt/freetype -> 
../Cellar/freetype/2.9.1

ls -l /usr/local/opt/freetype/lib

-r--r--r--  1 bpabbott  admin  791032 May  1 14:34 libfreetype.a
lrwxr-xr-x  1 bpabbott  admin      19 May  1 14:34 libfreetype.dylib -> 
libfreetype.6.dylib
drwxr-xr-x  3 bpabbott  admin      96 May  6 14:05 pkgconfig

Any ideas what may have changed?
