The S010 platform built properly, and the 'transition' folder with our markers is present here: /data/disk/tn/static/transition-network-d6-s010/sites/all/modules/contrib/gmap/markers
So the last 'non-standard' thing with our modules has been resolved and this ticket is able to just track the updates as they come in now. Reassigning to Sam for now, and updating main description so the current/best practice TN.org platform build numbers are documented.
Sam: I'll stay CCed on this ticket so can answer questions and help out as needed. Otherwise we're in great shape so it's all yours! (or delegate as you see fit!)
