FreeBSD and libusb

[Jan Dakinevich]

There are some difficulties when porting software, that depends on libusb
and
check for it with pkgconfig, because there is no .pc file in a base system.
But
what do you think about idea to change devel/libusb so file libusb-1.0.pc
file
would be created via port? IMO it will provide opaque way for porting and
don't
break compatibility in earlier version of FreeBSD.
