Hey, it's only a week since I said I'd take care of it "tomorrow"
:-). Actually I've looked at it more than once and the object
inheritance stuff is really driving me loopy. It appears that
File::Spec::VMS::eliminate_macros corrupts its own object reference
and then fails when it tries to invoke itself.
Here's where the object reference goes kaflooey:
$self = {} unless ref $self;
Since $self is the string 'File::Spec' it is not a reference, so it
gets overwritten with an empty, unblessed object. I have no idea
what the original intent behind this was. Then a few lines later it
tries to invoke itself via the nonexistent object:
File::Spec::VMS::eliminate_macros(/perl_root/lib/File/Spec/VMS.pm:45):
45: return join ' ', map { $self->eliminate_macros($_) } split /\s+/, $path;
DB<9> s
Can't call method "eliminate_macros" on unblessed reference at
/perl_root/lib/File/Spec/VMS.pm line 45.

The self-invocation of eliminate_macros only happens if the argument
has whitespace in it, and apparently the funny stuff at the end of
'[.ExtUtils.MakeMaker]\x{a}' is considered whitespace. I will try to
see what purpose that serves, if any, though it may be a red herring
in getting this to work.
