About the version of bison

[562462894]

Hello!
I have downloaded and installed the bison-3.0.tar.gz. But it shows 'bison 2.3' 
when I check the version of my bison.
Cause the version of bison I could not continue to install my thrift.
I don't know what happened to the bison-3.0? Or I have done something wrong 
when installing the software?
Waiting your answer!
Hope it soon!
Thanks!
