Need help to install an updated application.

[Barny Sanchez]

Dear Team,

I have tried and tried and failed in my attempts to do what I want.
I want to install and run socat in Leopard (10.5.2).  The version that  
ports installed is 1.4.2, but it is broken in Leopard.

As per the link http://trac.macosforge.org/projects/macports/ticket/13733 
  I should update to socat version 1.6.0.1 and disable termios in  
Leopard.

I really need help with the update part.  As I do "sudo port upgrade  
socat" this doesn't get updated to the latest version.  I also tried  
it with the application Port Authority but only the version 1.4.2 is  
available.

If I run "sudo port livecheck socat" the output displays:
socat seems to have been updated (port version: 1.4.2.0, new version:  
1.6.0.1)

Nevertheless, I am totally ignorant in the way to perform the upgrade.  
I know this is a lot to ask but I need a "for dummies" help here,  
cause I am very new to macports. How do I install socat 1.6.0.1?

Thanks so much!
