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.
