Sandeep,

not much is needed as BIND 9's ./configure script handles it for you 
when jemalloc and jemalloc-devel packages are installed.

Just check that after ./configure is run, there are the following two lines:

     Optional features enabled:
         Memory allocator: jemalloc

Once BIND 9 is compiled, run "ldd /path/to/named" and look for the 
jemalloc line, it should look similar to this:

     libjemalloc.so.2 => /lib64/libjemalloc.so.2 (0x00007f895f200000)
