Comment (by mascguy):

 Another example from today, 2021-05-17, for port `py-apache-beam`;
 [https://github.com/macports/macports-ports/pull/11044 PR 11044 - py-
 apache-beam: Update to version 2.29.0]:

 {{{
 2021-05-17T16:42:49.3114950Z Installing 342 dependencies of py39-apache-
 beam:

 2021-05-17T19:17:38.8274350Z Installing dependency (342 of 342)
 'py39-pymongo' with variants '' (requesting '') ... [OK]

 }}}

 Dependency installation time was 2 hours, 42 minutes, for the first
 subport build attempt.
