Comment(by jmr at macports.org):

 This problem only occurs with upgrade, where the depspecs are taken from
 the PortIndex, and not with install, where they are taken directly from
 the Portfile. The backslash in `\${prefix}` is there in the PortIndex, so
 it looks like the bug is either in the portindex command, or in the way
 data is loaded from the PortIndex.
