I updated pkg_add on one of my boxes and now pkg_add doesn't work because
my tar doesn't have --fast-read. (My work-around will be to change my
tar.)

revision 1.8 of pkgsrc/pkgtools/pkg_install/files/add/perform.c forces
--fast-read. It previously used:

  #if defined(HAVE_TAR__FAST_READ)

Should all implementations of tar have --fast-read??
