Hi ,this might be a newbie question and I don't know if it's the right  
place to ask here:  
I use opensuse11.1 and it has it's ruby1.8.7 rpm installed , later I  
tried to compiled a ruby 1.9 on the machine.now when I type :  
ruby -v  
It shows  
ruby 1.9.1p0 (2009-01-30 revision 21907) [x86\_64-linux]

then all of my gem installed under ruby 1.8.7 lost. since I just want  
to try 1.9 and some gem will have problem under 1.9 .so I want to set  
the default ruby still be the ruby1.8.7 . how could I do that ?

my ruby1.8.7 has the path :/usr/bin/ruby  
ruby 1.9 has the path : /usr/local/bin/ruby

thank you guys!

If you change your PATH variable to start with /usr/bin and after  
that you put /usr/local/bin, then I think you will be able to use Ruby 1.8.  
Bye!
