Hi there

In trying to install termios in my home server (which uses Debian  
testing) using gem and I get the following error:

# gem install --include-dependencies termios

in /var/lib/gems/1.9.0/gems/termios-0.9.4 for inspection. Results  
logged to /var/lib/gems/1.9.0/gems/termios-0.9.4/gem\_make.out

I don’t know where OpenFile is located in Debian, can you help me  
please?

Thanks in advance
