(as answered in the bug database but at an unrelated bug) these are apps errors, they fail to check if an extension is available before calling the associated functions. I'll check in a fix next week if noone beats me to it. The error message is slightly confusing though as it's not exactly an "implementation error" but expected behaviour. Could it be changed to something less drastic?

That is just standard code to avoid potential problems with creating default Mesa shader objects. There is zero (functional, only some ifdefed out leftovers from the copy of r300 driver) code for actually implementing these extensions, nor is it even possible (in a useful way).
