[PD] Gridflow Camera problem

[Fanouris Moraitis]

Hi all,

After I finally installed (thanks to your help) Griflow 08.04 on a Mac
Os 10.4.7
when I try any example that has input from camera (eg
motion_detect.pd) it does not work but instead I have the following
error

error: RuntimeError: can't do that: file not open
/Users/fan/gridflow/../gridflow/format/main.rb:167:in `check_file_open'
/Users/fan/gridflow/../gridflow/format/main.rb:216:in `_0_bang'
/Users/fan/gridflow/../gridflow/format/main.rb:167:in `send_in'
/Users/fan/gridflow/../gridflow/format/main.rb:167

I am using a firewire camera (dv camera).
Do I have to install any other libraries?
Does it have to do anything with the fact that when I installed
gridflow o did ./ configure --no gem08 --no gem09?

thanks
