 Hello, I need to install gcc6 on my Mac and the system tries to install
 its dependencies as well:

 {{{

 }}}

 I also linked the Homebrew gcc to the system's gcc:
 ln -s gcc-11 gcc

 {{{
 gcc --version

 and:

 {{{
 sudo port -n upgrade --force libxml2
 }}}



 but still I get

 {{{
 Error: Failed to build libgcc10: command execution failed
 }}}

 after trying to install gcc6 that is needed for the software I am planning
 to install.

 I heard gcc6 is not going to work on M1 Mac but I think the software needs
 to work with that. Is there any solution to this problem?

 Thanks
