Comment:

 I think I've finally realized what the problem is. Some [comment:3 earlier
 output] you posted says:

 {{{
 MacPorts base version 2.3.99 installed,
 }}}

 That means you're running a version of MacPorts trunk, not the released
 version 2.3.3. And I think the particular problem you're experiencing with
 `{os.platform}` not existing was introduced in r140015 on September 6 and
 fixed in r140050 on September 7. You just got unlucky by building MacPorts
 trunk during that time. So you should just need to update the Subversion
 working copy of MacPorts base that you used to install MacPorts trunk
 originally, and configure and build and install it again, like you did
 originally.

 After you do that, hopefully MacPorts will work properly, and you can then
 sync properly, which will show you what ports are outdated, and then you
 can upgrade the outdated ports, which will fix the minicom problem by
 rebuilding it against ncurses 6.

 If you're going to use MacPorts trunk instead of the released version, you
 have to expect that things will be broken from time to time, and make sure
 you keep your installation up to date.
