OPENSSL_1.0.1 Error When Executing Job Inside Jenkins - shell

Question

I've written a python script using scrapy to crawl a site, and I'm trying to set up a job through jenkins to call the script nightly (this way it's very easy to see the output).
The machine I'm running jenkins on is a bitnami VM inside google compute.
I set up the command to run through the shell command in jenkins, and it's failing with the following error:
Building on master in workspace /opt/bitnami/apps/jenkins/jenkins_home/jobs/Scrape and Import myco/workspace [workspace] $ /bin/sh -xe /opt/bitnami/apache-tomcat/temp/hudson4165433582945317339.sh

I'm perplexed because when I run the same command (as my user and the user jenkins is running under, tomcat) I don't get this error, the script works fine.
I suspect this may have to do with the script being executed inside apache, but I'm at my wits end and googling hasn't turned up any obvious solutions.
Any idea as to how to solve this?

Answer 1

symbol EC_GFp_nistp521_method, version OPENSSL_1.0.1 not defined in file libcrypto.so.1.0.0
It looks like you are running a python compiled with OpenSSL 1.0.1 with a libcrypto from OpenSSL 1.0.0. It might be because you are running with a different python (at least compiled against a different OpenSSL version) but include files from your local python installation which expects the newer OpenSSL.
