test is failing with libjpeg pkg is missing

[khemendra0]

Hi,
I have installed all prerequisite and running test:
DATA_ROOT=./datasets/ae_photos name=style_cezanne_cpu_pretrained model=one_direction_test phase=test gpu=0 loadSize=256 fineSize=256 resize_or_crop="scale_width" th test.lua

Below is error for libjpeg pkg not installed.
But when trying to install it is already installed.

loading previously trained model (/root/torch/CycleGAN/checkpoints/style_cezanne_cpu_pretrained/latest_net_G.t7)
use InstanceNormalization
