You're running the shell's built-in version of pwd, which
apparently doesn't support the --help or --version arguments. This
works for me:

$ /bin/pwd --version
pwd (GNU coreutils) 5.2.1

built-in pwd implementations can be confusing as they will in some
circumstances return a different directory to /bin/pwd, if you have cd'd
through a symlink. e.g.

$ mkdir a && ln -s a b
$ cd b
$ pwd
/tmp/b
$ /bin/pwd
/tmp/a
