What version of Ruby should I use now (January 2010)?

I have vanilla Mac OS X Leopard that comes with 1.8.6.

I am new to RoR, so I will follow the tutorials online. Can I find problems after them when using later versions of Ruby?

I am currently looking at this one that mentions 1.8.6 and 1.8.7 - http://www.railstutorial.org/book

The 1.8.x series (mainly 1.8.6) is still very widely used and is likely to remain that way for at least a year or so; 1.9 is slowly moving to. Although there are some significant differences between them, for the most part, everything you can do in 1.8, you can also do in 1.9.

Many of the more complex bits, such as blocks and lambdas, get a bit of make-up, but otherwise the tutorials for 1.8 will still refer to 1.9 for the most part. However, you are likely to run into problems if you use stones and libraries from 1.8 to 1.9.
