I did find this:
http://www.makehuman.org/doc/node/alpha_7_creating_a_custom_rig_with_makerig.html
But am really new to all this rigging and animation, will look at it though and see if I can figure any of it out.
add:
Looking at that ‘tutorial’ for making a custom rig, it points to makehuman/data/rigs as where the rig goes… in there is a .json file that contains the data for the rigs. I wonder if just knowing the proper ‘roll’ for some of them can fix the rig?
As an example from that file:
"bones": {
"Root": {
"head": "Root____head",
"parent": null,
"reference": null,
"roll": -1.4193105697631836,

},
"ball_l": {
"head": "ball_l____head",
"parent": "foot_l",
"reference": "toe1-1.L"],

},
