This is a bug in SunOS.  There is a standard fix in the MIT X11R5
source tree as mit/util/misc/dlsym.c, which I appended to this
message.  Just compile and link against this file and all will be well
(at least this bug will be fixed, no comment on any other bugs you
might have).

 * Stub interface to dynamic linker routines
 * that SunOS uses but didn't ship with 4.1.
 *
 * The C library routine wcstombs in SunOS 4.1 tries to dynamically
 * load some routines using the dlsym interface, described in dlsym(3x).
 * Unfortunately SunOS 4.1 does not include the necessary library, libdl.
 *
 * The R5 Xlib uses wcstombs.  If you link dynamcally, your program can
 * run even with the unresolved reference to dlsym.  However, if you
 * link statically, you will encounter this bug.  One workaround
 * is to include these stub routines when you link.
