Unknown IO error from XMLSEC1
When executing the command "xmlsec1 --list-transforms" the first line of the output is "error : Unknown IO error." I opened a case with XMLSEC1 and the main dev there says this particular error is coming from libxml2. I am not sure how to further troubleshoot. libxml2-2.7.6-21
[root@<hostname>]# xmlsec1 --list-transforms

The expected output of that command is :
[root@CentOS ~]# xmlsec1 --list-transforms
