------------------------+-------------------------
 On Mavericks, I’d like to build `libgsm @1.0.22 +universal`, since it is
 currently a library dependency of the `gstreamer1-gst-plugins-bad` port.
 At this time, it fails in the building phase of the `i386` architecture,
 emitting an error when trying to build the `./bin/toast` executable:

 }}}

 In the attached `main.log` file, note that no `-arch` option was provided
 to the compilation lines that were used to build the object files for both
 `./lib/libgsm.a` and `./bin/toast`; perhaps it’s using the `x86_64`
 architecture by default, and thus failing when trying to build for the
 `i386` architecture.
