- Xorg 6.9 uses the .so extension instead of .a for the server extensions.
Fix the pkg-plist for that 
- Remove the USE_REINPLACE since it is no longer needed 
Please note that 4.X users will probably suffer from this as a side
effect, however, taking them into account will further complicate the
Makefile logic, which is already pretty hard to follow. Since I warned
4.X users about removing support for that old release of FreeBSD (and
since I'd be really suprised to find out there's someone still using
4.X as their desktop) more than 8 months ago, plus we're not obliged to
support ports on 4.X anymore, I think we can live with it.
Once again, I'm encouraging people using this port use it with modern
FreeBSD version and modern graphics card.
