Something must be wrong with the syntax you suggested. Since I don't 
know my jhbuild at all, I don't know how to fix this.

Traceback (most recent call last):
   File "/Users/jlaroche/Source/jhbuild/jhbuild/config.py", line 194, in 
     execfile(filename, config)
   File "/Users/jlaroche/.config/jhbuildrc", line 462, in <module>
   File "/Users/jlaroche/.config/jhbuildrc-custom", line 54
     module_cmakeargs["boost"] = "-DCMAKE_CXX_FLAGS=" . 
os.environ["CXXFLAGS"] . " -std=c++17"
SyntaxError: invalid syntax
jhbuild: could not load config file
