For me, using an up-to-date MacPorts system, compilation of LilyPond
from the git works as follows.

(1) Clone `lilypond.git` or clean an existing repository with

      git clean -fdx 

(2) Configure LilyPond with

      ./autogen.sh --noconfigure
      && ./configure \
         CC="ccache clang-mp-9.0" \
         CXX="ccache clang++-mp-9.0" \
         GUILE=/opt/local/bin/guile18 \
         GUILE_FLAVOR=guile-1.8 \
         --prefix="/foo/bar" \
         
--with-texgyre-dir="/usr/local/texlive/2020/texmf-dist/fonts/opentype/public/tex-gyre"
 \
         --with-flexlexer-dir="/opt/local/include" \
         --disable-documentation

    Remarks:

      . Adjust `--prefix` to whatever is suitable for you.
      . Using `ccache` is optional.
      . Slightly older clang versions should work, too.
      . I use TeXLive directly, so please adapt the path to the
        TeX-Gyre fonts as necessary if you use the MacPorts packages
        of TeXLive.

(3) Build and install with

      make all && make install

(4) Run lilypond as

      LTDL_LIBRARY_PATH=/opt/local/lib \
      PATH=/foo/bar/bin:$PATH \
      lilypond <file>
