The pesign-obs-integration package is pulled into the OpenHPC build already as can be seen from the line [ 107s] [164/165] installing pesign-obs-integration-10.0-29.1 pulled from the link in the description. I may have misunderstood - I was under the impression that the # needssslcertforbuild should only be used when a signing server is active. I will tell the openHPC folks to branch the package and build it with this line added and see if this helps.
