Man pages are installed in the wrong place.
spidey ~ # ls /usr/local/man?
/usr/local/man1:
ntpdig.1 ntpq.1 ntpsweep.1 ntptrace.1
/usr/local/man5:
ntp.conf.5 ntp.keys.5
/usr/local/man8:
ntpd.8 ntpfrob.8 ntpkeygen.8 ntpleapfetch.8 ntptime.8 ntpwait.8
The proper place would be:/usr/local/man/man1, etc.
