I have done some at that time of evening (getting people up at this time of year to catch working in morning "golden hour" is nigh impossible). Most of my portraiture is done under studio lights these days, so digging back in my memory, here are a few things to watch for.
1. Absolutely take a white card shot before every new lighting situation - golden hour gives you very funkly lighting, but in portraiture getting natural skin tones is the priority. If you haven't got a white card or grey card as a target, a piece of white paper does in a pinch. The important thing is you want a neutral colour and some papers have optical bleaches that react with UV light and actually have a blue cast. With the sun down quite low, the UV component of the light will be minimal, so you should be okay. I've done this and gotten away with it. Use the target to set you white balance in post.
If shooting RAW, do this in post. If shooting jpeg; take a picture of the target in the light you will be using for the shot. Make sure the target fills the frame and set your custom white balance that way. When the sun sets, the colour temperature changes quickly as the sun gets close to the horizon, so frequent shots of the target are a must to get your skin tones correct.
2. Be aware of colour "pollution"; standing under a tree will throw a green colour cast (if the leaves are out, not the situation where I am), standing too close to a red barn will reflect red light on the subjects, etc.
3. Play with the direction the light hits your subjects; soft shadows make for interesting portraits.
4. Have fun!
