Hit the same problem.


The package doesn't compile with USE=-readline.  Temporary workaround is to add USE=readline.

Relevant code:

#ifdef HAVE_LIBREADLINE
		char *rlbuffer = readline(": ");
		if(!rlbuffer) break;
		string svalue = rlbuffer;
		free(rlbuffer);
#else
		fputs(": ", stdout);
		if(!fgets(buffer, 1000, stdin)) {b_ret = false; break;}
		string svalue = buffer;
#endif

It looks like this was fixed in v3.22.0, here's the commit fixing it:
