I am trying to install Gentoo prefix on MacOS X (Mojave and Catalina). The system is fresh installed and mostly clean (Xcode is obviously an exception). bootstrap-prefix.sh produces a series of error messages, then fails. I am trying to fix these errors one by one. This reports deals with the following error message: !!! unknown compiler. This error happens in function configure_toolchain(). My invocation of 'gcc --version' produces the following output: Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple clang version 11.0.0 (clang-1100.0.33.17) Target: x86_64-apple-darwin18.7.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin which obviously is slightly different with what the script expects. The fix is trivial. I will be attaching a patch. Reproducible: Always Steps to Reproduce: 1. ./bootstrap-prefix.sh Actual Results: !!! unknown compiler Expected Results: No error message and the version of clang is properly determined. Obviously I cannot provide 'emerge --info' output.
Created attachment 668363 [details, diff] Fix for clang-11 version check Tested on cleanish MacOS 10.14.6 with Xcode 11.3.1(11C505).

I went with a slightly different approach, to be a bit more specific and hopefully not match something unexpected in the future.
