It's $PREFIX/lib/gnucash/, not $PREFIX/lib/libgnucash*, but that's not your
problem.
It's because C++17 is set in GnuCash's CMakeLists.txt and boost defaults to
building for C++14. I'd forgotten that I'd pushed that to the public master
branch. I think the simplest way to rebuild it for you would be to add
module_cmakeargs['boost'] = '-DCMAKE_CXX_FLAGS=' . os.environ['CXXFLAGS'] .
' -std=c++17'
to jhbuildrc-custom then run
jhbuild buildone --force --clean boost
If that doesn't work on its own try doing the buildone again but stop it and
tell it to wipe the directory and start over.

John Ralls
