Comment (by ryandesign):

 Your log says:

 > {{{
 > Updating man page man/autoreconf.1
 > }}}

 which mine on macOS 10.15 does not. The port patches some files that make
 the build system think it needs to regenerate autoreconf.1, but the port
 also `touch`es autoreconf.1 which should set its timestamp to be equal to
 or newer than that of the patched files, which should avoid the need to
 rebuild it. Can you confirm whether `touch` is working correctly? Not the
 command line `touch` command but the MacPorts Tcl implementation of
 `touch`.
