Comment (by MarcusCalhoun-Lopez):

 Replying to [comment:9 kencu]:
 > The underlying problem is not Xcode 10, but the fact that when a port
 lists a dependency on `ld64`, on `10.13` any version other than `ld64
 +ld64_xcode` is likely to cause troubles.
 Fair point, but I wold humbly suggest that this ticket is not the way to
 address this issue.\\
 Since this is not an octave specific issue, I would suggest we close this
 ticket and either
 * Open a dedicated ticket that CCs the interested parties
 * Address this on the mailing list
 * Open a pull request with the changes you propose
 * Magically find a way for Apple to update the open source versions of
 [https://opensource.apple.com/tarballs/ld64/ ld64] and
 [https://opensource.apple.com/source/cctools/ cctools]
 Otherwise, I worry that this ticket is destined to be forgotten and
 forever open.
