Because the path:-style dependency is to be used if all the ports providing the specified file are equivalent, but they are not, due to the differing library version numbers.

A user who tries to use qt4-mac with libjpeg-turbo will get a crashing program, if they got a binary of qt4-mac from the packages server, which was build with jpeg.

Whatever we decide regarding the jpeg library should be done across all of MacPorts simultaneously in a single commit.
