Thanks for your feedback, Emanuel.

Yes, PATH is correct; however, I did use a different method to show its 
value:

Here's my Makefile:

--{--cut here--
which:
	echo "PATH=$(PATH)"
	ls -ld /home/evansl/anaconda3/bin/pdf2txt.py
	which pdf2txt.py
--}--cut here--
and heres the make invocation from within emacs:
--{--cut here--
-*- mode: compilation; default-directory: 
"~/prog_dev/python/pdfminer/pdfminer/" -*-
Compilation started at Tue Feb 13 17:47:05

echo $PATH ; make -k which
/home/evansl/anaconda3/bin;/home/evansl/miniconda3/bin;/home/evansl/dwnlds/depot_tools/depot_tools:/home/evansl/dwnlds/gsrc.top/install/bin:/home/evansl/bin:/opt/OpenPrinting-Gutenprint/sbin:/opt/OpenPrinting-Gutenprint/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
echo 
"PATH=/home/evansl/anaconda3/bin;/home/evansl/miniconda3/bin;/home/evansl/dwnlds/depot_tools/depot_tools:/home/evansl/dwnlds/gsrc.top/install/bin:/home/evansl/bin:/opt/OpenPrinting-Gutenprint/sbin:/opt/OpenPrinting-Gutenprint/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin"

--}--cut here--
and before doing all that, I created a ~/.bashenv using the
name pattern you gave in your post (~/.$(SHELL)env):

--{--cut here--
evansl@lje-OptiPlex-9020:~$ pwd
/home/evansl
evansl@lje-OptiPlex-9020:~$ cat .bashenv
#let emacs know the environment
. .bashrc
evansl@lje-OptiPlex-9020:~$ tail .bashrc
fi

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

# added by Miniconda3 installer
export PATH="/home/evansl/miniconda3/bin:$PATH"

# added by Anaconda3 installer
export PATH="/home/evansl/anaconda3/bin:$PATH"
evansl@lje-OptiPlex-9020:~$
--}--cut here--

So, I still can't figure how to get emacs to find pdf2txt.py in
home/evansl/anaconda3/bin/ by setting PATH somehow.
