Macports 1.8, creating my stable environment

[Scott Haneda]

Hello, I have a Power Mac Dual G5, it's current state is that I  
develop on it, and have the 1.7 branch of MacPorts installed.

I have no problems blowing away /opt/local and starting clean.  There  
are a few sites that I would back up, and a few databases I would  
maintain, but outside of that, there is not a lot going on.

I want to start using this as a main production machine, and migrating  
old sites to it in an effort to retire some older machines.

Should I update to 1.8, or would it be better to install clean?

As it is now, my only needs are Apache2, MySql5, and php current.  I  
just need to know that those things will build clean and without  
trouble.  I can afford a few hours downtime on this machine as it is  
now.

What is your suggested course of action?  I have been reading some  
reports of troubles here with 1.8, and want to make sure I am not  
getting into a situation in which I will be stuck, or have to just  
install 1.7 and go from there.

Once I build this machine out, it would be best to not have to shove  
1.8 ontop of 1.7 just for the sake of being clean about it.

Thank you.
