[Debian-med-packaging] Bug#894213: How to make sure PATH is set correctly (Was: foo FTBFS with dh-python >= 3.20180313)

[Andreas Tille]

Hi again,

sorry for nagging again but what else than I did in

   https://salsa.debian.org/med-team/snakemake/blob/master/debian/rules

can I do to set PATH in pbuilder.  Possibly I've understand all your
hints incorrectly - the PATH is just not set inside pbuilder chroot. :-(

Kind regards

     Andreas.
