Maybe the failure occurred because I deleted /usr/bin/../libexec/darwin/x86_64/as.

Please take a look at it. Thank you. I took a look. It confirms the problem is because you deleted that assembler. as: assembler (/usr/bin/../libexec/gcc/darwin/x86_64/as or /usr/bin/../local/libexec/gcc/darwin/x86_64/as) for architecture x86_64 not installed Installed assemblers are: /usr/bin/../libexec/gcc/darwin/ppc64/as for architecture ppc64 /usr/bin/../libexec/gcc/darwin/ppc/as for architecture ppc /usr/bin/../libexec/gcc/darwin/i386/as for architecture i386 Your existing compiler is an x86_64 compiler, so it needs the x86_64 assembler. You could try passing the -m32 flag to the bootstrap compiler so it only outputs 32-bit code, but it would probably be easier to restore the assembler you deleted.
