The gringo port still can't be compiled after passing the stdlib=libc++ to clang

[心如烛光]

Hi,Ryan!
    Thank's for your help.I have tried the process, which is posted in the "https://trac.macports.org/wiki/LibcxxOnOlderSystems"


First,I have installed the newest 2.3.3 macport and edited the macports.conf with the 
words


"cxx_stdlib         libc++
buildfromsource    always
delete_la_files    yes"
and try "sudo port clean gringo""sudo port install gringo".


But it doesn't work.


Then I tried:"uninstall all ports that use C++"
and the message it returns:
"Preparing Uninstall...
Uninstall Began...
Uninstall Failed...
Reason: ErrorMissingBundle
"
Why?Meanwhile,I don't think that to uninstall all the ports that use C++ is a good way to solve the problem since I have so many ports and dependencies,which will be uninstalled and installed.
Is there any other way to install the gringo?


Yours!
