Comment (by ballapete):

 On `Big Sur` a bug exists when `dblatex` is built. A `make check` in `gtk-
 doc`s source directory shows this failure:

 {{{
 Traceback (most recent call last):

 }}}

 The reason is not that `/opt/local/bin/dblatex` does not exist but that
 the script starts with

 {{{
 #!/opt/local/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.83.8
 }}}

 The correct interpreter is of course
 `/opt/local/Library/Frameworks/Python.framework/Versions/3.8/bin/python3.8`!
