First, install the developer's version of the ncurses library.  Then change 
directories to imidiacy-source, and issue:

user@host$ gcc -O3 -lm -lncurses -o <bin_path/imidiacy> bitwise.c speaker_fns.c term_fns.c record.c program.c

To get permission to the PC speaker, issue as root:

root@host# chown root <bin_path/imidiacy>
root@host# chmod u+s <bin_path/imidiacy>

Refer to the manual about the severe security risk involved in giving 
programs suid root permissions!
