 Upgraded to Catalina.
 Uninstalled MacPorts entirely.
 Reinstalled MacPorts and all of the ports I still need.
 Molden is the only one that failed. Log file attached (main.log).

Comment:

 According to the log the problem is:

 {{{
 src/xwin.c:4393:17: error: implicitly declaring library function 'tolower'
 with type 'int (int)' [-Werror,-Wimplicit-function-declaration]
 :info:build             if (tolower((unsigned char)needle[j]) !=
 :info:build                 ^
 }}}

 implicitly declared function errors are new in Xcode 12 beta. (I presume
 you have installed the command line tools for Xcode 12 beta.) I can work
 on fixing this. If you want to avoid these errors in other ports, install
 the Xcode 11.5 command line tools.
