 This failure is caused by go installing /opt/local/include/ar.h which
 includes a struct ar_hdr that contains a 'name' member, not an 'ar_name'
 member. This shadows the system's /usr/include.ar.h, which is what gmake
 expects to be compiled against.

 Credit to jmr_mp in IRC for helping me hunt that down.
