OK. I have figured out how to run plenv from a cron to run plerd, like this:

PLERD_HOME=_path_to_plerd_src
* * * * * /path/to/plerd_pub.sh

Where plerd_pub.sh is:

#!/bin/bash -l
PLERD_HOME=/home/jjohn/src/plerd_taskboy3000
cd $PLERD_HOME && ./bin/plerdcmd -P

Clunky, I know. Worth it for me, since plenv offers crazy flexibility.

Also, the source file name from bear isn’t going to be a problem.
