[PROBLEM] Unable to compile unrar-nonfree because of man

[pix3l]

Hi,

I'm unable to compile unrar-nonfree.
The process quits with the following error:

Code:

To me, it seems like the make process needs the full version of man and not the BusyBox version of it.
Is there a way to install the full man, so I can finally compile unrar?
