Log Message:
Update p5-Module-ScanDeps to 0.68.

Changes:
[Changes for 0.68 - 2006-10-25]
* Added special case for PerlIO.pm. If PerlIO.pm is needed, require
  PerlIO::scalar, too, because it can be used "under the hood".
  (Roderich Schupp)
* Added some File::Spec'ness. (Steffen Mueller)
* Refactored the %Preload mapping code into _get_preload so that
  the PAR -M %Preload fix would work. (Steffen Mueller)

[Changes for 0.67 - 2006-10-24]
* Added @IncludeLibs which is used alongside @INC for searching modules.
  (David Romano)
* Won't pick up Tk as a dependency for Term::ReadLine any more.
  You can stop laughing now!

[Changes for 0.66 - 2006-09-24]
* Fixed another bug in Module::ScanDeps::Datafeed which would break
  run- and compile-time dependency scanners if $ENV{PERL5LIB} entries
  had trailing backslashes. Thanks to Steven Mackenzie for pointing
  this out.
* Added some documentation and comments to M::SD::Datafeed for the sake of
  future maintainers.

[Changes for 0.65 - 2006-09-24]
* Fixed bug in Module::ScanDeps::Datafeed which would die() in 0.64.

[Changes for 0.64 - 2006-09-22]
* Upgraded to Module::Install 0.64
* Added warning of missing modules when -V is in effect (scandeps.pl).

  an option to scan_deps.

[Changes for 0.61 - 2006-06-30]

* Added test for POD correctness.

[Changes for 0.60 - 2006-05-23]
