Yep.

At this point, outside of eliminate_macros() and fixpath() themselves,
catfile() and catdir() are the only places using them. So we may be able to
seperate them.

That's easy, stick:
return $path unless $self->isa('ExtUtils::MakeMaker');
in fixpath() and eliminate_macros(). Though that's < ideal.
What would be ideal is if we could have MM override catdir() and catfile()
and perform the fixpath/eliminate_macro mumbo jumbo on the input/output of
File::Spec's methods rather than doing it inside File::Spec.
Lemme make sure I understand why fixpath() and eliminate_macros() are
necessary. eliminate_macros() takes something like this:
$self->{PREFIX} = '[this.that]';
$self->{FOO} = '[foo.bar]';
print $self->eliminate_macros('$(PREFIX)$(FOO)');
and makes it come out like '/this/that/foo/bar'? This is necessary because
a lot of the work normally done by shell commands from the Makefile on Unix
(and thus macros are expanded) is done inside MM_VMS?
And fixpath()... I don't really get how fixpath() is different from
eliminate_macros().

This is nothing. You should look at the MakeMaker linker code. *shudder*
