# This file is read by man to configure the default manpath (also used
# when MANPATH contains an empty substring), to find out where the cat
# pages corresponding to given man pages should be stored,
# and to map each PATH element to a manpath element.
# It may also record the pathname of the man binary. [This is unused.]
# The format is:
#
# MANBIN		pathname
# MANPATH		manpath_element	[corresponding_catdir]
# MANPATH_MAP		path_element	manpath_element
#
# If no catdir is given, it is assumed to be equal to the mandir
# (so that this dir has both man1 etc. and cat1 etc. subdirs).
# This is the traditional Unix setup.
# Certain versions of the FSSTND recommend putting formatted versions
# of /usr/.../man/manx/page.x into /var/catman/.../catx/page.x.
# The keyword FSSTND will cause this behaviour.
# Certain versions of the FHS recommend putting formatted versions of
# /usr/.../share/man/[locale/]manx/page.x into
# /var/cache/man/.../[locale/]catx/page.x.
# The keyword FHS will cause this behaviour (and overrides FSSTND).
# Explicitly given catdirs override.

# This file is also read by man in order to find how to call nroff, less, etc.,
# and to determine the correspondence between extensions and decompressors.

Hi Again:

It is most definitely possible to see duplicate man pages in Manual. I have Xcode 4.6, 5.1.1, and 6.1 installed. I added MANPATH statements for each into my /Private/etc/man.conf and not only did "apropos" and "waits" command line commands show the three, but so did Manual as can be seen below via my DropBox links. Your man.conf looked pretty much as initially installed does, so, not sure if your original query was from results (which setting $MANPATH can also affect) or just speculative. Anyway, now we know that duplicate entires are indeed possible.

MANPATH /usr/share/man
MANPATH /usr/local/share/man
MANPATH /usr/X11/man
MANPATH /Applications/Xcode5.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/share/man
MANPATH /Applications/Xcode6.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/share/man
MANPATH /Applications/Xcode4.6.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/share/man
