ErlInterface (sorry, here goes another question)

I whipped up a sample ei program that connects to a remote node and attempts
to send a message to a registered process on that node. The message is simply
the atom 'hello_world'.
Attached is the Makefile and main.cpp src file. This builds (OpenBSD 3.3
Current running OTP R9C-0):
rpettit@REDACTED /home/rpettit/EI # gmake
g++ -c -I/usr/local/lib/erlang/lib/erl_interface-3.4/include main.cpp
g++ main.o -L/usr/local/lib/erlang/lib/erl_interface-3.4/lib -lerl_interface -lei -lpthread -o ei-test
/usr/local/lib/erlang/lib/erl_interface-3.4/lib/libei.a(ei_connect.o): In function `ei_connect_init':
/home/rpettit/downloads/erlang/OTP-R9C/otp_src_R9C-0/lib/erl_interface/src/connect/ei_connect.c:491: warning: sprintf() is often misused, please use snprintf()
/usr/local/lib/erlang/lib/erl_interface-3.4/lib/libei.a(show_msg.o): In function `ei_trace_printf':
/home/rpettit/downloads/erlang/OTP-R9C/otp_src_R9C-0/lib/erl_interface/src/misc/show_msg.c:81: warning: vsprintf() is often misused, please use vsnprintf()
Disregard the error messages (or don't ;-), it is complaining about "unsafe"
string routines being called from the ei library.
The problem is the program produces output that seems to indicate I goofed a
rpettit@REDACTED /home/rpettit/EI # ./ei-test
hello_worldLooks like it worked!
If I comment out the call to ei_reg_send() then I only see:
Which seems to indicate that the trouble is with the call to ei_reg_send(). I
thought my sample was pretty much straight out of the docs, with minor mods
(the atom sent, etc).
Any suggestions welcome.
P.S. Perhaps someone has done work with ei (sample apps, etc) that they would
like to post a link to?
