summary

Build CRuby from source: checkout a stable tag, install OpenSSL, run ./configure, then make, make check (≈14,000 tests) and make install; set PATH and GEM_HOME. Use lldb / gdb / Xcode debuggers to break into C functions called from Ruby. Edit C files to define classes/methods (data_Make_Struct, rb_define_method, NUM2LONG, LONG2NUM), or add extensions. Measured speedups: Fib in C ≈30× faster, prime ≈17×, some C routines and grid creation hit 19–50×.
