I get this:

:info:configure checking whether we are cross compiling... configure: error: in `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_sysutils_smartmontools/work/smartmontools-5.40':
:info:configure configure: error: cannot run C++ compiled programs.
:info:configure If you meant to cross compile, use `--host'.

So it seems like I need to track down the Portfile and set:

platform darwin powerpc {
	configure.args-append \

But this is not exactly clear from the example and lack of an options list. I'm not seeing a Tcl file related to this package at all, so I have no idea how to proceed.
