Explicitly disabling extensions was reported as making it build with the 
option enabled:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250315

Unluckily it is causing problems, so the option is now broken at runtime 
as you reported.

Not sure if there is an easy fix or if fixing it (apart from updating to 
a newer virtualbox release) is at all possible at this point.

An idea I'm going to try is manually aligning the broken includes to the 
new dri provided ones. Please give me a little time to cook up a patch 
for you to test.

Not much to debug, that symbol is actually absent. But enabling the code 
to include that symbol causes the build to fail.

Don't think it's related.
