You know have 2 versions installed. This means that you did not configure things properly for your system.
I don't know if this is for Redhat or Debian but I would remove your previous version first. Best to wait for a packages version to become availiable. If you still want to compile from source (i assume this version is not availiable as a package yet ?) then do :
# ./configure --help
to check your intall options,
Your probably need to add --prefix=/usr to your configure options
# ./configure --prefix=/usr
