how to install man pages?

[Mike Wright]

Hi all,

I've two fc6 boxes that for whatever reason have different parts of the 
man pages installed.

One has the man pages for mdadm.conf(5) but none for mdadm.  The other 
has man pages for mdadm.conf(5) and mdadm(8).  "man 8 mdadm" refers to 
mdadm(4) which exists on neither.  Note that neither box is running a 
raid array!? (%#*&!;D)

Can anybody enlighten me on how to install some/any/all man pages for 
some/any/all applications?

Many TIA,
Mike Wright :m)
