[wlug] When man-db goes thug ... help?

Hi guys Never seen this before, need a hand.  Fairly fresh Debian 8 install, fully updated, running as root. root(a)ROOTCA:~/ca# man opensslroot(a)ROOTCA:~/ca# man -kroot(a)ROOTCA:~/ca# which man/usr/bin/manroot(a)ROOTCA:~/ca# man --helproot(a)ROOTCA:~/ca# ... When I execute man, it doesn't give me anything, and just returns me to the command prompt.  Not even man --help will return a response. I've purged and reinstalled man-db, ensured that ncurses-base is installed, even checked the size of man (106912 bytes), and checked dmesg for any segfaults... there's just nothing I can find anywhere.   Any ideas?  Thanks in advance.
