Version 0.6.4

  @prefix@/sbin/pkg_add is used instead of just pkg_add.
  This fixes a problem under NetBSD (with default PATH) where
  /usr/sbin/pkg_add doesn't support flag -D needed by nih.

  ~/.nih directory is created in the very beginning.
  This fixes 'cd: ~/.nih: No such file or directory' problem
  on fresh systems.
