From looking at the docs for Safe I don't think you are passing the correct arguments: 
$safefuncs->share( 'Barcode::DataMatrix' );
$safefuncs->share_from('main', [ 'DataMatrix2d' ]);

[download]
'Barcode::DataMatrix' is being treated as a function name. You could try: 
$safefuncs->share_from( 'Barcode::DataMatrix', \@safeops );
$safefuncs->share_from( 'main', [ 'DataMatrix2d' ]);

From the docs: 
share (NAME, ...)

[download]
This shares the variable(s) in the argument list with the compartment... Each NAME must be the name of a non-lexical variable, typically with the leading type identifier included. A bareword is treated as a function name. 
share_from (PACKAGE, ARRAYREF)

[download]
This method is similar to share() but allows you to explicitly name the package that symbols should be shared from. The symbol names (including type characters) are supplied as an array reference.
