Comment(by mlk@…):

 Thank you for being attentive to this request.  That said, I liked the
 original version better, when file names weren't changed; I can no longer
 use this port -directly- with GNU Radio, instead finding some indirect
 means to get GR's configure script to detect the presence of libusb-legacy
 (without changing the configure script to look for libusb-legacy.pc).  I
 understand that there was a conflict between the compat and legacy (as I
 mentioned earlier), and hence a need to do -something- quickly.

 My preference is keep complete filename and functionality backwards
 compatibility of both LIBUSB legacy and compat (NOT at the same time), and
 insert a check in the Portfile of each to make sure the other isn't
 installed (and error out if so with a brief message about picking one or
 the other).  Those ports which rely upon one or the other could then look
 for the file $prefix/lib/pkgconfig/libusb.pc and be happy if installed (by
 either port) -- and it would be the user's choice as to which to install
 and use: the faster but just external-API compatible compat, or the slower
 but guaranteed to be functional internal and external legacy.

 This latter seems like a more robust and functional solution: one which
 does not require changes to any projects making use of the older libusb.
