libvpx on macOS

Hi,

Anyone know what the fix is for this? ffmpeg4 wants it unless removed via 
options.

macOS 10.15, clean install, current pkgsrc.

libtool: compile:  sh strip_fPIC.sh yasm -f macho64 -I./ 
-I/Users/john/pkgsrc/multimedia/libvpx/work/libvpx-1.10.0/ 
vp9/encoder/x86/vp9_quantize_ssse3_x86_64.asm -o 
vp9/encoder/x86/vp9_quantize_ssse3_x86_64.asm.o >/dev/null 2>&1
libtool: compile:  clang++ -O2 -isysroot 
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk 
-mmacosx-version-min=10.5 -m64 -arch x86_64 -I. 
-I/Users/john/pkgsrc/multimedia/libvpx/work/libvpx-1.10.0 -c 
vp9/ratectrl_rtc.cc  -fno-common -DPIC -o vp9/.libs/ratectrl_rtc.cc.o
clang: warning: include path for libstdc++ headers not found; pass
