Pdist/pmirror need meaningful error messages.

[thomas]

As shown by buggy #104, I opt (again) that pdist and pmirror should die with a more verbose error message.

not :  

     die "$filename: $!\n";

but rather:

    die "$filename: $!, stopped";

This would present a line number, and would tell an uninitiated user that something is definitly wrong.
