Port linux_dri has incorrect packaging list

[Yuri]

I have linux_dri-7.0_1 installed.
pkg-plist has the line /compat/linux/usr/X11R6/lib/libGL.so.1 and 
'pkg_info -L linux_dri-7.0_1' shows 
/compat/linux/usr/X11R6/lib/libGL.so.1 but there no such file in the 
file system.
Insteas there is:
ls -l /compat/linux/usr/lib/libGL.so.1
lrwxr-xr-x  1 root  users  15 Jun  6 13:05 
/compat/linux/usr/lib/libGL.so.1 -> libGL.so.180.60

As a result automatic port upgrade of may ports depending on Linux 
libGL.so fails and attempts to reinstall linux_dri and fails because 
it's already installed.
portupdate looks for /compat/linux/usr/X11R6/lib/libGL.so.1 for some 
reason, it's not there and it decides to install linux_dri and fails.

Please fix this,
Yuri
