On all logins to RHEL/CentOS nodes I get now this error:

manpath: invalid option -- q
manpath, version 1.6d

usage: manpath [-adfhktwW] [section] [-M path] [-P pager] [-S list]
    [-m system] [-p string] name ...

  a : find all matching entries
  c : do not use cat file
  d : print gobs of debugging information
  D : as for -d, but also display the pages
  f : same as whatis(1)
  h : print this help message
  k : same as apropos(1)
  K : search for a string in all pages
  t : use troff to format pages for printing

      (if no name given: print directories that would be searched)
  W : as for -w, but display filenames only

  C file   : use `file' as configuration file
  M path   : set search path for manual pages to `path'
  P pager  : use program `pager' to display pages

The problem actually is here:

# cat /etc/profile.d/rudder-agent.sh
# Rudder profile entries, to add the agent to the
# PATH and its manpages to the MANPATH

# 1 - Add CFEngine binaries to the PATH

PATH=${PATH}:/var/rudder/cfengine-community/bin
export PATH

# 2 - Build a MANPATH with our manpages in it

## If $MANPATH is already defined, use it, or build
## a new one from scratch if it does not
if type manpath >/dev/null 2>&1
then
    MANPATH=$(manpath -q):/opt/rudder/share/man
elif [ ! -z "${MANPATH}" ]
then
    MANPATH=${MANPATH}:/opt/rudder/share/man
else
    MANPATH=/opt/rudder/share/man
fi

export MANPATH
