I can't reproduce here. Does 'lib/Gtk2/Ex/MindMapView.pm' contain the 
string $VERSION anywhere else in the file? I doubt that's the problem 
here though because this looks like an error from version/vxs.

I used Module::Starter to make a little 'Foo' distro.

Foo.pm
package Foo;
use version; $VERSION = qv('0.0.1');
1;

Makefile.PL
use ExtUtils::MakeMaker;
WriteMakefile(
     'PL_FILES' => {},
     'NAME' => 'Foo',
     'VERSION_FROM' => 'lib/Foo.pm',
)

with:

perl 5.8.7
ExtUtils::MakeMaker 6.30
version 0.57

But, it works fine for me. Can you provide a minimal test case that 
exercises the problem?
