No.

Cwd  was first released with perl 5
Data::Dumper  was first released with perl 5.005
ExtUtils::Install  was first released with perl 5.002
ExtUtils::Manifest  was first released with perl 5.001
ExtUtils::Mkbootstrap  was first released with perl 5.001
File::Basename  was first released with perl 5
File::Compare  was first released with perl 5.004
File::Copy  was first released with perl 5.002
File::Find  was first released with perl 5
File::Path  was first released with perl 5.001
File::Spec  was first released with perl 5.005
Getopt::Long  was first released with perl 5
IO::File  was first released with perl 5.00307
Test::Harness  was first released with perl 5
Text::ParseWords  was first released with perl 5
Test::More  was first released with perl 5.007003

That build_requires on Test::More is erroneous, since it is bundled
in the distribution.  It should be removed:  (untested)

If possible, it would be better to make YAML itself work on 5.005_03
than to create a YAML::Simple.  But neither satisfies the goal of
having M::B have no non-core dependencies.
