mailutils: update to version 3.12 - building from command line but failing to build using macports

[Giuseppe 'ferdy' Miceli]

	Ciao,

as mentioned this afternoon on irc/rocket.chat i stumbled in a weird behaviour which i am too newbie to understand and i would really appreciate any help about.

context: couple of years ago, i submit the Portfile for GNU mailutils 3.6, which is still in the repository, which i needed to build emacs from git.
having changed hardware and osx version, i found out it doesn’t build on osx 11.x (https://ports.macports.org/port/mailutils/summary), thus i thought to update the portfile to the last version 3.12.

status: i can successfully build mailutils 3.12 on macOS 11.3.1 20E241 with Xcode 12.5 12E262 from command line yet using macports (whist it configures correctly with the same configure output summary), it fails to build.

all the relevant files are here: http://ferdy.it/mp-mailutils-3.12/ 

thank you very much in advance for any support you can provide.

cheers,
