R_io.so missing , installed with afni on Mac OS

I’m trying tp install AFNI on Mac OS,
I got the error R_io.so missing.
I tried using the command ldd @GetAfniBin/R_io.so >>> error command not found
for the second command about the path (d) on your page, I got
[1] “/Users/fatemahsakr/abin/R_io.so”

dyn.load(ll)

Thanks a lot in advance

What is the output of the following command (assuming that your AFNI binaries are under ~/abin/)?

otool -L ~/abin/R_io.so
