You're right, of course -- it's a bug in the linkage loader on the
platform in question.  NetBSD/vax has it:

$ uname -a
NetBSD varg.i.eunet.no 1.5T NetBSD 1.5T (VARG) #4: Thu Apr 5 23:38:04 CEST 2001
     root@varg.i.eunet.no:/usr/src/sys/arch/vax/compile/VARG vax
$ cat > foo.c
int main (int argc, char **argv) { readline(); }
$ cc -o foo foo.c
/tmp/ccFTO4Mu.o: Undefined symbol `_readline'referenced from text segment
collect2: ld returned 1 exit status
$ cc -o foo foo.c -ledit
$ echo $?
0
$ ./foo
/usr/libexec/ld.so: Undefined symbol "_tputs"in foo:/usr/lib/libedit.so.2.5
$ echo $?
1
$ ldd foo
foo:
        -ledit.2 => /usr/lib/libedit.so.2.5 (0x181b000)
        -lc.12 => /usr/lib/libc.so.12.74 (0x182d000)

The basic difference is this: hackers build things, crackers break them.
