dirname: missing operand error when starting

[wuatanabe]

Hello,
I ma trying to get your server running, but I get the following error:

/merlke/scripts/merlke start
dirname: missing operand
Try `dirname --help' for more information.
../merlke/scripts/merlke: line 5: md5: command not found
{"init terminating in do_boot",{undef,[{merlke_runner,execute,[["start"]]},{init,start_it,1},{init,start_em,1}]}}

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()

Note I have the required dependencied
(installing merkle I add to maually add the ebin dir to make it works).
