Comment:

 The installation appears to be trying to write directly into
 /opt/local/share/grass78, bypassing the destroot. Indeed MacPorts does and
 should prevent that. Ports must install into the destroot.

 We didn't see the same build failure on our build server. I'm not sure why
 it failed to build on your system. We need to investigate and fix that.

 The reason why you didn't get our prebuilt binary is that you're using the
 +python37 and +postgresql10 variants. The default postgresql variant
 became +postgresql12 as of grass7 @7.8.1 and the default python variant
 became +python38 as of grass7 @7.8.2. If you don't mind using postgresql12
 instead of postgresql10 and python38 instead of python37, you could avoid
 the problem by running `sudo port clean grass7` and `sudo port install
 grass7 +python38 +postgresql12`.
