[developers] updated debian, logon fails

[Damir Cavar]

Hi Joshua,

obviously your Allegro CL has a CLIM component (interfacing with X-Windows or other GUI environments), and it requires a PNG-library libpng in a specific version. This lib actually should be part of the Allegro distribution (I do not use Allegro, can't tell), so, most likely, either you have to reinstall Allegro or just set a path to the libs, maybe an environment variable that points to the folder where the libs are.

Best

DC
