Problem with posix-spawn when setting up

When running bundle, I was faced with the following error:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

compiling posix-spawn.c
posix-spawn.c:226:27: error: incompatible function pointer types passing 'int (VALUE, VALUE,
posix_spawn_file_actions_t *)' (aka 'int (unsigned long, unsigned long, void **)') to parameter of
type 'int (*)(VALUE, VALUE, VALUE)' (aka 'int (*)(unsigned long, unsigned long, unsigned long)')
[-Wincompatible-function-pointer-types]
        rb_hash_foreach(options, posixspawn_file_actions_operations_iter, (VALUE)fops);
                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

note: passing
argument to parameter 'func' here
void rb_hash_foreach(VALUE hash, int (*func)(VALUE key, VALUE val, VALUE arg), VALUE arg);
                                       ^
1 error generated.
make: *** [posix-spawn.o] Error 1

make failed, exit code 2

To get round this error I had to run: gem install posix-spawn -- --with-cflags="-Wno-incompatible-function-pointer-types" before running bundle

Hope this helps someone
