The libxpm4 dependancy is in the Maemo sdk/tools repository so I replaced the install file on the download page to keep the number of installed repos down for anyone who already had that one.

Pressing the power key will dim the screen if a secondary key is required to unlock. Problem is that if dim timeout is equal to blank timeout then the screen skips the dim stage and goes straight to blank. You will need to set the secondary key to none until I release a fix.
