Author: Deri James <deri@chuzzlewit.myzen.co.uk>

    [BuildFoundries]: Fails if neither ghostcript nor
    URW fonts are installed.
    
    * font/devpdf/util/BuildFoundries.pl: When the change to hold paths
    in an array, rather than a delimited string (see commit
    4ae4aeb6555f4f16c28fcb03eb1f56577826054c), the FindGSpath
    subroutine should return a pointer to an empty array when the
    call to ghostscript fails, rather than return an empty string,
    as was done previously.

    thanks to Bruno Haible for the report.
