It is now.

  CFLAGS='-Os -I/opt/local/include/LegacySupport -arch x86_64'
  LDFLAGS='-L/opt/local/lib -Wl,-headerpad_max_install_names -lMacportsLegacySupport -arch x86_64'

An example compilation command is:

  cc -Os -I/opt/local/include/LegacySupport -arch
  x86_64 -O3 -g -Wall -pedantic -DETCDIR=\"/etc\"
  -DRAWHIDE_NAME=\"rawhide\" -DRAWHIDE_PROG_NAME=\"rh\"
  -DRAWHIDE_VERSION=\"3.1\" -DRAWHIDE_DATE=\"20221011\"
  -DHAVE_PCRE2=1 -DHAVE_ACL=1 -DHAVE_POSIX_ACL=1
  -DHAVE_MACOS_ACL=1 -DHAVE_EA=1 -DHAVE_MACOS_EA=1
  -DHAVE_FLAGS=1 -DHAVE_MAGIC=1    -I/opt/local/include
  -c rhdir.c

And the final link command is:

  cc -Os -I/opt/local/include/LegacySupport -arch
  x86_64 -O3 -g -Wall -pedantic -DETCDIR=\"/etc\"
  -DRAWHIDE_NAME=\"rawhide\" -DRAWHIDE_PROG_NAME=\"rh\"
  -DRAWHIDE_VERSION=\"3.1\" -DRAWHIDE_DATE=\"20221011\"
  -DHAVE_PCRE2=1 -DHAVE_ACL=1 -DHAVE_POSIX_ACL=1
  -DHAVE_MACOS_ACL=1 -DHAVE_EA=1 -DHAVE_MACOS_EA=1
  -DHAVE_FLAGS=1 -DHAVE_MAGIC=1    -I/opt/local/include
  -o rh rhcmds.o rh.o rhparse.o rhdir.o rhdata.o
  rhstr.o rherr.o -L/opt/local/lib
  -Wl,-headerpad_max_install_names
  -lMacportsLegacySupport -arch x86_64 -L/opt/local/lib
  -lpcre2-8     -lmagic

And with debugging on, everything looks correct until
the error:

  openat(parent_fd=3, path=.git)
  openat: dir_fd 4
  fdopendir(dir_fd=4)
  dir entry ./.git/branches
  fstatat(parent_fd=4, path=branches)
  rh: fstatat ./.git/branches: Bad file descriptor

The "bad" file descriptor is 4 which was returned by openat.
That what's it looks like on other systems that work. Mysterious.

cheers,
