Something is wrong with installing ROS on my IntelGalileo board?

edit

I wanted to operate the ROS on my IntelGalilo board and followed the tutoria IntelGalile/HydroGalileoInitialInstall. However, it had something wrong when I handled the step of "bitbake image-full".

Pseudo is not present but is required, building this first before the main build ERROR: OE-core's config sanity checker detected a potential misconfiguration. Either fix the cause of this error or at your own risk disable the checker (see sanity.conf). Following is the list of potential problems / advisories:

Please install the following missing utilities: makeinfo

ERROR: Execution of event handler 'check_sanity_eventhandler' failed

How can I solve this problem. Thanks for any help.
