 I'll have to make a setup for that. Might take some days due other tasks.
 
 It might be that I setup the jail tree to not use compat. But rather have
 a complete linux system tree at jail root. Ie linux files in /bin/ not
 /compat/linux/bin/
 
 That way when software like Xilinx tries to modify/access /usr/X11R6 files it
 get's the linux files it expect.
