cannot read manpages

[Luca Ferrari]

Hi,
a fresh 7.04 installation results in the following:

root at backup:~# man ssh-add
Reformatting ssh-add(1), please wait...
man: can't execute /usr/bin/pager: No such file or directory
man: command exited with status 
65280: /usr/bin/zsoelim /tmp/zmanuZLfuD | /usr/bin/tbl | /usr/bin/nroff -mandoc -rLL=111n -rLT=111n -Tutf8 | /usr/bin/pager -s
man: can't remove /tmp/zmanuZLfuD: No such file or directory

Any idea of what package should I install (or reinstall) to get the man pages 
working?

Thanks,
Luca
