What steps will reproduce the problem?
1. add new armature in blender
2. rotate bone by 45 degrees and animate it around its normal axis
3. port that to ogre meshy and see that its not using normal but global axis 
for rotation

What is the expected output? What do you see instead?
rotation to be like in blender

here is a blend file with the animation i try to get into ogremeshy with lots 
of different results but never the correct one.
maybe you can either tell me how to do that or you can find where the bug is.

I think that I am also having this problem. I am trying to export an animated 
character to my game, but when I load the animation in it is messed up.

I have been trying to debug the code for the last 2 days now and I believe it 
is something to do with the axis swap (x,y,z)->(x,z,-y). Before the latest 
version I could export animations correctly if I used the (x,y,z)->(x,y,z) 
export option. I am also having trouble with exported cameras facing the wrong 
way when this swap is enabled, but I guess that is a bug for another report.

Attached is a blender file with the character that I am trying to export. He 
lifts his leg and drops it again.

It appears to fix the animation issues when I export using the default axis 
swap export (-x z y). It fails to export correctly when using x y z. I want to 
use x y z because the exporter incorrectly exports camera orientation correctly 
using anything other than x y z.

Also, I looked at the code that you are using when exporting the skeleton, you 
have: "self.flipMat = 
mathutils.Matrix(((1,0,0,0),(0,0,1,0),(0,1,0,0),(0,0,0,1)))" for 'xz-y'. 
Shouldn't it be "self.flipMat = 
mathutils.Matrix(((1,0,0,0),(0,0,1,0),(0,-1,0,0),(0,0,0,1)))"? Maybe I'm not 
understanding how that section works correctly yet.
