Many thanks,  I couldn?t find the right way to convince R that freetype was installed in /opt/X11 but installing it
from http://mac.r-project.org/libs/ into /usr/local worked immediately without any change in my Makevars file.

I presume 'R 3.7.0' is R-devel: it is not released and may never be released under that version.

to compile from source with a ~/.R/Makevars file that looks like this:
CC=/usr/local/clang8/bin/clang
CXX=/usr/local/clang8/bin/clang++
LDFLAGS=-L/usr/local/clang8/lib
CPPFLAGS=-I/usr/local/clang8/include -I/opt/X11/include/freetype2

I suspect you don't want the second: if you have pkg-config it should find include paths for you.

FC=/usr/local/gfortran/bin/gfortran
FLIBS=-L/usr/local/gfortran/lib -lgfortran
As usual, the last challenge seems to be to get rgl installed.  Compilation _seems_ to go
smoothly, but I now see:
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object '/Library/Frameworks/R.framework/Versions/3.7/Resources/library/00LOCK-rgl/00new/rgl/libs/rgl.so':

Perhaps you should show the linking line.  A similar setup works for me:

configure: Darwin, so ensuring /opt/X11/bin is at the head of the PATH...
checking for pkg-config... yes
...

Do you have pkg-config (it is not a standard part of macOS, but is available on SU's site -- see the R-admin manual)?  You may need to set its path: for rgl I used

PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig

(which should be the default) but for a few packages (Cairo gdtools rsvg)

PKG_CONFIG_PATH=/opt/X11/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib/pkgconfig

/usr/local/clang8/bin/clang++ -std=gnu++11 -dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module -multiply_defined suppress -L/Users/ripley/R/R-devel/lib -L/usr/local/clang8/lib -L/usr/local/lib -o rgl.so ABCLineSet.o BBoxDeco.o Background.o ClipPlane.o Color.o Disposable.o Light.o LineSet.o LineStripSet.o Material.o NULLgui.o PlaneSet.o PointSet.o PrimitiveSet.o RenderContext.o Shape.o SphereMesh.o SphereSet.o SpriteSet.o String.o Surface.o TextSet.o Texture.o Viewpoint.o api.o assert.o callbacks.o device.o devicemanager.o fps.o ftgl.o geom.o gl2ps.o glErrors.o glgui.o gui.o init.o par3d.o pixmap.o platform.o pretty.o render.o rglmath.o rglview.o scene.o select.o subscene.o win32gui.o win32lib.o x11gui.o x11lib.o -lGLU -lGL -framework GLKit -framework OpenGL -dylib_file /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib -L/usr/local/lib -lpng16 -L/usr/X11/lib -lX11 -L/usr/local/lib -lfreetype -L/Users/ripley/R/R-devel/lib -lR -Wl,-framework -Wl,CoreFoundation

so that is statically linking libfreetype from /usr/local/lib and installed from https://mac.r-project.org/libs/freetype-2.5.5-darwin.13-x86_64.tar.gz . And that provides a freetype2.pc file, so

% pkg-config freetype2 --cflags
-I/usr/local/include/freetype2 -I/usr/local/include/libpng16
% pkg-config freetype2 --libs
-L/usr/local/lib -lfreetype



There is a comment somewhat after this about rgl requiring XQuartz, but I have  XQuartz 2.7.11 so I don?t
think that this is the problem.  Apparently, there is still a freetype problem, however I?m out of my depth at this
point.   Any suggestions would be most welcome.
