Comment (by adsche):

 This happened to me too.
 The hanging process is apparently building the Sphinx documentation:


 {{{

 But no output seems to be generated in any of the folders on the command
 line.
 Therefore I wanted to try the +python39-docs variant but it did still try
 to install +docs (I did clean in between).

 **`port install cmake -docs` worked though**, but +python39 seems to imply
 +docs, unfortunately.

 I am not sure whether it is actually hanging or just taking really long,
 but I did not see any output generated in the output directory for 30
 minutes.
