Looks like you’re using an older version of Perl. Change the code to:

{
    package Math::Matrix;
    ...

[download]

This should remove the compile error. However, the inverse calculations will likely be incorrect. If so, upgrade Math::Complex to the latest version (1.59), and you should be set to go.
