libjemalloc.so.2: cannot open shared object file:

>>> import pyarrow
Traceback (most recent call last):

ImportError: libjemalloc.so.2: cannot open shared object file: No such file or directory

$LD_LIBRARY_PATH has libarrow_jemalloc.a along with other libraries including libarrow.so, libparquet.so, libparquet_arrow.so. Pyarrow was built using ----with-jemalloc and parquet-cpp was cmake-d with
-DPARQUET_ARROW=ON

Also, noticed that arrow/python documentation has been cleaned up with the installation instructions having the coda approach only .Is this the only supported way going forward ?
