 Replying to [comment:8 pjkim00@…]:
 > If reinstalling macports as described above installs gnutar and it
 builds correctly, then no problem.

 It does not. Building MacPorts causes it to determine what tar command is
 available. On previous versions of OS X, it determined that `gnutar` was
 available, and used it. On Mavericks, it will determine that `tar` is
 available and use it. The problem is when you build MacPorts on an earlier
 OS and then try to use it on Mavericks. Don't do that.

 > The only scenario I can understand is if textmate2 actually does not
 need gnutar but explicitly lists it as a dependency. Is that the case?

 textmate2 does not list a dependency on gnutar. But the file
 bin/create_default_bundles_tbz in the textmate2 source code runs the
 command `gnutar -cf "$TBZ_DST~" "$BZIP2_FLAG" -C "$BUNDLES_DST" "Managed"`
 which of course fails if `gnutar` does not exist. I don't see any gnutar-
 specific flags in use there, so I surmise that using `tar` instead of
 `gnutar` in that script would work fine. And yes, as suggested earlier in
 this thread, that should be reported to the developer of textmate2 so that
 he can make that change.

 > It seems that a LOT of ports require gnutar so I don't think that
 removing gnutar from just the textmate2 build script will do much for the
 overall macports experience.

 Assuming that MacPorts has been built on the OS it is being used on, then:
  * Any port that declares a dependency on gnutar is fine.
  * Any port that doesn't declare a dependency on gnutar and doesn't need
 gnutar is fine.
  * Any port that uses `tar` is fine.
  * The problem is only ports that use gnutar but don't declare a
 dependency on it, like textmate2. That's what this ticket is about.
