Errors while cythonizing siever_params.pyx #125

I try to install g6k on Mac OS (14.2.1, intel processor) and when bootstrap.sh reaches the stage

[2/2] Cythonizing g6k/siever_params.pyx

and making the file cpuperf.lo I get the following error

./simd.inl:133:10: error: argument to '__builtin_ia32_psrldqi128_byteshift' must be a constant integer

this error repeats a few times and causes

Command 'make' returned non-zero exit status 2

after error I try to run the tests and get the module error

ModuleNotFoundError: No module named 'g6k.siever_params'

(I also add a txt file with all the outputs starting from the siever_params.pyx compilation)
