[unpack a ruby 1.8.6 tarball and cd into it]  
./configure --prefix=/path/to/ruby186  
make && make install  
/path/to/ruby186/bin/ruby -v

I beleive the one click installer allows installing in different  
locations.

However, you would have to modify your path when you want to use a  
different ruby or not set your path at all and run it by full name.

I suspect there might be problems if you set your path to point to one  
version of ruby and run another one as windows use path to look up  
shared libraries.

Thanks
