Comment (by Gandoon):

 Just a small update, I didn't mention it in the original submission, the
 failure seems to occur in the ''destroot'' phase.\\
 The tail end of the log file reflects this:

 Apart from several warnings, the rest of the actual ''build'' phase seems
 to have been correctly executed prior to the stopped on Error. The
 `Building pyobjc-core...` initially seemed to indicate to me that a build
 stage failed, but if I read the log correctly, this is indeed in the
 ''destroot'' phase, thus I don't think it is directly related to older
 closed tickets such as #63084 or #63087, as they both failed in the
 ''build'' phase. Please advice if I am wrong in that assumption.

 As far as I understand it, the ''destroot'' phase should perform an
 ''install'' procedure in the build directory, after the completion of
 which the whole package is moved into its final positions. \\
 Could this have something to do with which user is performing the
 operation? I performed the build as root (sudo), and several of the steps
 are indeed performed as or chowned to the user ''macports''.
