Ok, all seems to work here on my Linux distro Xubuntu 20.04:

• XML::CanonicalizeXML
  

  sudo apt install libxml2-dev
  cpan XML::CanonicalizeXML
  [download]

• XML::XPath (this also installs XML::XPath::XMLParser i think)
  

  cpan XML::XPath
  [download]

• Crypt::OpenSSL::RSA
  

  cpan Crypt::OpenSSL::RSA
  [download]

There may be additional dependencies/libraries you have to install in your Linux distro. I've tested this on my office dev machine, on which i already have a huge amount of stuff installed.
