[mapserver-users] sudden inability to find non-missing libttf.so.4.0

[gisweb at lmi.net]

List:

Mapserver 3.5 installed successfully on a FreeBSD platform and was merrily 
pumping out beautiful interactive web maps.  Until yesterday.  For no apparent 
reason, mapserv now reports that it "Can't find shared library 'libttf.so.4.0'."

Apache's error_log reports the following:
> tail -5 error_log
ld.so failed: Can't find shared library "libttf.so.4.0"
[Wed Oct  9 18:07:09 2002] [error] [client 32.102.91.129] Premature end of scrip
t headers: /usr/home/gisweb/www/cgi-bin/mapserv

And yet, the libttf.so.4.0 library is alive and well exactly where mapserv 
expects to find it, as evidenced by the following ldd output and subsequent ls -
l check of the directory location.  (The same is true of all other libraries 
listed by ldd.)

> ldd mapserv
mapserv:
        -lm.2 => /usr/lib/libm.so.2.0 (0x2007a000)
        -lpng.3 => /usr/local/lib/libpng.so.3.0 (0x20094000)

And so, dear reader, comes the big question--why does the formerly triumphant 
mapserv no longer find the libraries that were once so beloved?

Could a change to other libraries in the /usr/lib or /usr/local/lib directories 
have shifted the tenuous alliances between formerly complimentary open-source 
products?

Flashes of brillance welcomed with open arms.
