--------------------------+-------------------------
 Hi all,

 I must say at the beginning that i'm not a guru in these kind of things so
 please be patient if I ask no sense questions.
 I'm trying to install virt-viewer port [https://ports.macports.org/port
 /virt-viewer/] on macOS Monterey 12.0.1 on a mac mini M1.
 I followed the guide on this link [https://www.macports.org/install.php]
 before to execute the installation command for virt-viewer port.

 I got an error during the installation of virt-viewer port on libgcc11
 build execution, I already checked "Problem Hotlist" and did port clean).

 ''Error: Failed to build libgcc11: command execution failed
 Error: See
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc11/libgcc11/main.log
 for details.
 Error: Follow https://guide.macports.org/#project.tickets if you believe
 there is a bug.
 Error: Processing of port virt-viewer failed''

 Looking into the main.log file I see:

 }}}

 and looking into config.log I see

 }}}

 I read old threads on the web regarding gcc and Clang but they were
 referring to old OSX versions so I'm not sure that was the same case..
 Anyway this is the output of gcc --version command:

 {{{
 Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
 --with-gxx-include-

 InstalledDir:

 }}}

 I attach both main.log and config.log files.

 Thank you in advance for your support.

 Best regards
