The long answer:
- this is an error from pkg-config
- pkg-config stores version information in .pc files
- xorg uses descriptive names for these modules, which don't always match the 
capitalization or lib prefix of the port, but sometimes does.
- /usr/ports/Mk/bsd.xorg.mk maps the .pc files to the port directories

Therefore, to find out:
$ grep xi.pc /usr/ports/Mk/bsd.xorg.mk
xi_LIB_PC_DEPENDS=              ${LOCALBASE}/libdata/pkgconfig/xi.pc:
${PORTSDIR}/x11/libXi

Problem with today's modular software: they start with the modules
    and never get to the software part.
