Do you want to use locally found installer scripts and archives to install WikiWorkbenchContrib and any dependencies.
If you reply n, then fresh copies will be downloaded from this repository.? [y/n] y
Package repository set to http://foswiki.org/pub/Extensions

Code should be more tolerant to invalid file locations in the manifest.

BuildContrib should probably prevent this from happening in the first place, but regardless, Configure should not crash.
