It's already terminated. This is the process that remains:
91761 macports /opt/local/libexec/macports/bin/tclsh8.5 
/opt/local/bin/port -d install +logo

I can see a single child under it:
91820 macports (sh)
I cannot kill process 91820, even with sudo kill -9.

I just noticed now that if I'm patient and I wait long enough (~3 
minutes), the build actually "recovers" and continues.

I'm a bit lost here. The upstream shell build script, which runs a 
virtually identical `xcodebuild` command as this port, does not exhibit 
this behaviour.

I can provide build logs. I did not attach them here since I'm not sure 
if it is regular practice to send attachments to the list.

Any help would be much appreciated,
