Comment (by Schamschula):

 Unfortunately, xar 1.6.1 is also 4 years old...

 However, it is newer that xar-devel (@1.6_5).

 The port file needed a number of changes:

 1) replace $ID$ line with mode line

 2) use github PortGroup

 3) use worksrcdir

 4) remove unused xz dependency

 5) use_autoconf

 6) remove obsolete configure.args
