Things to try...

Edit /etc/ld.so.conf.d/local.conf and add "/usr/local/lib".
Create a sym link: "ln -s /usr/local/lib/libct.so.4 /usr/lib/libct.so.4"

I had run and "updatedb" and did a "locate libct.so.4" and located the file in the /usr/local/lib directory. However for some reason, it was complaining the file was missing. Eventually I did an "ldd /usr/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi/auto/DBD/Sybase/Sybase.so" and it said the file was missing. On several occassions I traced it back to looking in /usr/local and not checking /usr/local/lib. Easiest fix is usually the symlink. In this case, that did the trick.
