Hi - Just a follow up on the issue of zlib version.  I installed the 
1.1.4 version of zlib available via Fink and rebuilt everything. Using 
the newer version of zlib, I encounter the same problem (i.e. a 
segfault from htdig with a very deep stack trace). I did perform a 
distclean and verified the use of the 1.1.4 version libz via otool.
