Re: [EXTERNAL] Re: Interaction between lang/gcc10 and archivers/zstd

Intersting. I uninstalled the gcc10 package made with --without-zstd, removed the package from the packages/ directory and tried to reinstall with a clean Makefile. As I expected, it failed with the same issue.

Were any other packages installed between your unsuccessful and successful installs? I'm wondering if one of the tools used during configuration is a factor.

Thanks,

    'make' with no changes whatsoever completed without any problems.
