First of all, reinstall FPC so that /usr/local/bin/fpc is valid again. "fpc" is an independent program and can never be a symbolic link to a compiler binary. It supports parameters that the compiler binaries do not support. You cannot overwrite it with a symbolic link.

That's because ppcx64 on Mac OS X is an i386->x86-64 cross-compiler and the Makefiles are not designed for bootstrapping with cross-compilers. You can work around it by adding CPU_SOURCE=x86_64, but you can just as well build a new cross-compiler.

Lazarus cannot yet be compiled for x86-64 on Mac OS X (except if you compile it for GTK or Qt, possibly). Unless you are editing files that are larger than 1.5GB, it's unlikely you'd notice any difference either.
