 Hi. Trying to install gnuplot on a fresh MacPorts installation on MacOS
 Monterey, but it quickly fails when installing the dependency port
 "gindent". Looking at the error log, it seems that the compiler flags are
 too stringent, killing the build because a variable is declared but not
 used:

 {{{
 :info:build output.c:843:8: error: variable 'paren_level' set but not used
 [-Werror,-Wunused-but-set-variable]
 }}}

Comment:

 This kind of thing is the reason why we recommend ports don't build with
 `-Werror`.

 Since this isn't a MacPorts-specific problem, please report it to the
 developers of gindent at https://savannah.gnu.org/bugs/?group=indent.
