You don't need to create the link in /usr/X11R6/lib.
The problem is dlerror().

dlopen() _does not_ reset dlerror() state on sucess, it just returns
non NULL. So you must not check dlerror() for error condition, you
need check return result of dlopen(), and if it is NULL, then you need
use dlerror().
So, code in grace:
dlopen(library name, MODE);
Sorry,
I have reread manual page for dlerror() and found that it need clear
error state after call, but
dlerror() in src/libc/gen/dlfcn.c does not do this:
#pragma weak dlerror
const char *
dlerror(void)
{
return sorry;
}
So error is in FreeBSD libc, if I understand this correctly. I'll do

Apparently the dlopen() call in grace works fine
on Linux and others. But not with FreeBSD.
This is not a problem with the dlopen call *or* freebsd - the
problem is that it is asking for a library 'libXcursor.so.1.0'
