From past experience I know that this error might be caused by wrong Xcode version or not accepted license. However I deleted everything: Xcde, command line tools, and Mac Ports, reinstalled, accepted the license and am still getting this error. Also all the other ports seem to be working fine (git, neovim, bash, pass, redo, multimarkdown).
