Neither of those modifications should be needed, but the instructions 
referenced below should not be run if building in /usr. If the book says 
to run them unconditionally, then I've made a mistake when reorganizing 
the section a while back. I'm not in a position to look at it for the

I think for builds with a prefix other than /usr, it would be better to 
just add all three of the paths to the end and force a cache update in 
the configuration section (using 'cat >> /etc/mandb.conf << "EOF"' 
syntax). It should be tested by somebody who uses something other than 
/usr as the installation prefix. I'm still of the mind to completely 
drop the alternate prefix business for everything (the wiki is the place 
for differing opinions), but others seem to still want and use it, so it 
should stay as long as somebody is keeping an eye on it for breakage. I 
generally do keep it in mind, but only to a minimum as I do not actually 
test in an alternate prefix. Also, does mandb.conf support a 
source/include directive? Best would be to use the mandb.d/* method if
