several TeX distributions in the same box

[Your XEN ICT Team - Ricardo Rodriguez]

Hi all,

I'm using  MacBook box that is acting as workbench for a number of TeX 
distributions. I've also started LyX on the same box.

Please, how do I set up which LaTex distribution will be used by LyX? 
Thanks!

Best regards,
