python 2.7 - conda list doesn't show installed package -

i have been listing packages in environment using 'conda list'. list produced doesn't include packages know installed in environment, in case, flickrapi.

((getpics)) c:\users\rdebbout>conda list fl packages in environment @ c:\users\rdebbout\appdata\local\continuum\anaconda2\envs\getpics: pyflakes 1.1.0 py27_0

this pointing correct environment , if below, when in same environment, can import flickrapi without problem
