Doesn't say anything. But rsync is indeed run. I changed it to this
script:

#!/bin/bash

echo "run!"
echo "run!"

and

ural#  rsync -avv -e "ssh -l root" ./orig/ machine::module/
opening connection using: ssh -l root machine rsync --server --daemon .  (8 args)
rsync: server sent "run!" rather than greeting
rsync error: error starting client-server protocol (code 5) at main.c(1635) [sender=3.1.1pre1]

Using a higher debugging (with the real rsync):

ural#   rsync -a --debug=all4 -e "ssh -l root" ./orig/ machine::module/
FILE_STRUCT_LEN=24, EXTRA_LEN=4
cmd=ssh -l root machine=machine user=<NULL> path=module/
cmd[0]=ssh cmd[1]=-l cmd[2]=root cmd[3]=machine cmd[4]=rsync cmd[5]=--server cmd[6]=--daemon cmd[7]=. 
opening connection using: ssh -l root machine rsync --server --daemon .  (8 args)
msg checking charset: ANSI_X3.4-1968
[sender] safe_read(5)=0
rsync: did not see server greeting
[sender] _exit_cleanup(code=5, file=main.c, line=1635): entered
rsync error: error starting client-server protocol (code 5) at main.c(1635) [sender=3.1.1pre1]
[sender] _exit_cleanup(code=5, file=main.c, line=1635): about to call exit(5)
[sender] sending MSG_ERROR_EXIT with exit_code 5
[sender] send_msg_int(86, 5)

So rsync is run at the remote end but doesn't answer with the server
greeting the client expects.
