Thanks for the patch! If I may ask, what is the point of dot and doxygen
in the native-inputs? They don't seem to affect the result of the build
in any way.

Hi Jakub!

So sorry, I never received the email. Just came across your response at 
https://issues.guix.gnu.org.

They are for generating documentation. It was not enabled ,but it is now 
(see below).

I have revised the patch to involve the following:
[1] Update to 1.0.1.
[2] Enable documentation.
[3] Enable python binding.

Please find the attachment.

Regards,
RG.
