Hi Raghu,

Thanks for your reply.

I ran make install in my 9.1 directory again,and this time,the server
started but is giving errors in running the code which was running
earlier.Could you tell me a way in which I could remove both 9.1 and
9.2beta2 and build both from scratch and install them independently
this time?
