What happens if you adjust the entry for viewer_pdf in your personal
texdoc.cnf?  The one shipped with texlive says:

# Defaults depend on what is available on your system, as well as your desktop
# environment. Here are a few examples.
#
# %s is optional and stands for the filename.
#
# viewer_pdf = xpdf             # works
# viewer_pdf = xpdf %s &        # works even better

Maybe that helps getting rid of the env variable.

Best, Arash
