Hi Khem, Thanks for the (possible) solution. What I was really looking for is some way of finding out what changed with the addition of the OSTree directories that then caused the need for the additional libraries. Are there some tools that I don't know about that will help me find what is causing the gbm & gles2 to now be included when they are not necessary without the OSTree dirs.
