Lightning (For Thunderbird)

[James Griffin]

Hi,

I wanted to install Lightning from ports for use with Thunderbird but it 
appears there no longer is a port for this software. Is this the case; 
and if so, will there be at some point in the near future?

Failing that, is anyone else aware of Calendar software similar to 
Lightning that works well with Thunderbird?

Thanks for any suggestions. Cheers,

Jamie.
