Good Evening,
I just thought I would mention this on the listserv in case anyone else has
similar issues. When trying to install on Mojave, I was getting the
following error message:
ld: library not found for -lmc
It turns out it the compiler was looking for the /usr/include folder which
no longer exists with the most recent version of XCode Developer Tools and
Mojave. In order to get the installation to work, just install the include
folder from the following link instructions:
