Not with python3.7, as it lacks  python-3.7-embed.pc as follows:

# See: man pkg-config
prefix=/usr/pkg
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: Python
Description: Embed Python into an application
Requires:
Version: 3.7
Libs.private: -lcrypt -lintl -lpthread  -lutil -lm
Libs: -Wl,-R${libdir} -L${libdir} -lpython3.7
Cflags: -I${includedir}/python3.7

Later python versions do have the corresponding file and should work,
but I haven't tried them.

I was able to build the package by placing the above file in
work/.buildlinks/lib/pkgconfig and rebuilding in place (rm
work/.configure_done work/.build_done; rm -r
work/libpeas-1.26.0/output; make).
