--- Comment #1 from Dimitry Andric <dim@FreeBSD.org> ---
You should probably not set CXXFLAGS/LDFLAGS directly, as the port's CMakeLists
has a USE_ASAN option for this. E.g. this builds fine for me:

diff --git a/misc/py-pytorch/Makefile b/misc/py-pytorch/Makefile
index 9db96e4f4e9b..53d7c166a405 100644

exist, see https://github.
 MAKE_ENV+=     USE_CUDNN=0
 MAKE_ENV+=     USE_LAPACK=1 # needed on FreeBSD to run w/out GPU

 LDFLAGS+=      -lexecinfo

I don't know how to properly test the result, though. "make test" doesn't
appear to do much?
