Wake up or alarm from suspend

[wonder]

Hello.
In the past, I was used this soft:
https://launchpad.net/wakeup
For me perfect, works fine and wake up when I set.
Now, I want install but I can't because indicate that, some dependencies are missing.

I search alternatives, but only view the command: rtcwake

For me not work, I set and configure this command with differents methods but never wake up from suspend my computer.

You know similar program to wakeup for this?

Thanks in advanced!
