Is it actually in /lib64, or in a subdirectory of it?  I don't  
believe ld recurses.  Try:

   ldconfig -v

to see what it thinks it's searching, at least by default.

You can add more paths in /etc/ld.so.conf.d/ files.

[Labitt, Bruce] Bill, thanks for responding.  I was wondering why the
list was so quiet.  Everyone is really working hard, or on vacation?

Running as root, ldconfig sees libpcre.so in both /lib and /lib64.  /lib
is seen before /lib64.  What does this mean?

WRT adding paths, how does one name the file?  I presume the contents
are the desired path.
