Created attachment 228290 [details] v1 (use "git am") print/texinfo uses both CC values by default: 1. For itself, taken from $CC: https://git.savannah.gnu.org/cgit/texinfo.git/tree/configure.ac?h=texinfo-6.8#n194 2. For Perl extension (XS) modules, taken from Perl, unless PERL_EXT_CC is passed: https://git.savannah.gnu.org/cgit/texinfo.git/tree/configure.ac?h=texinfo-6.8#n55 https://git.savannah.gnu.org/cgit/texinfo.git/tree/tp/Texinfo/XS/configure.ac?h=texinfo-6.8#n77 If one wants to build a compiler (e.g. devel/llvm13) from ports while not having base compiler (cc) (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257622#c2), and using Perl built using older compiler which no longer exists (or, while having no base cc when using devel/llvm12 and Perl bootstrapped from pkg.FreeBSD.org), then a mismatch will happen, e.g.: 1: [...] checking whether the compiler supports GNU C... yes checking whether /usr/local/llvm13/bin/clang accepts -g... yes checking for /usr/local/llvm13/bin/clang option to enable C11 features... none needed checking whether /usr/local/llvm13/bin/clang understands -c and -o together... yes checking whether the compiler is clang... yes [...] 2: [...] checking for perl...

Sorry for not leaving a short reproducer, I'll get back to submitting a reproducer later after finishing some of my other tasks. I leave this PR here so the community can find this.
