the program header (from ld) should provide pointers to where the library
is, assuming that it actually was installed.  it might be that the linker
needs more on your system; eg:

/bin/sh ./libtool --tag=CC   --mode=link gcc -g -O2 -D_THREAD_SAFE -pthread    -g -O2 -D_THREAD_SAFE -pthread    -version-info 1:0:0 -version-number 1:0:0   -o libtacacs.la -rpath /usr/local/lib libtacacs_la-fdes.lo libtacacs_la-maxsess.lo libtacacs_la-md4.lo libtacacs_la-md5.lo libtacacs_la-packet.lo  -lpam  -lcrypt 
libtool: link: gcc -shared  -fPIC -DPIC  .libs/libtacacs_la-fdes.o .libs/libtacacs_la-maxsess.o .libs/libtacacs_la-md4.o .libs/libtacacs_la-md5.o .libs/libtacacs_la-packet.o   -lpam -lcrypt  -O2 -pthread -O2 -pthread   -pthread -Wl,-soname -Wl,libtacacs.so.1 -o .libs/libtacacs.so.1

see -rpath; make sure it added this on your system in a manner appropriate
for your installation.  if not; do it manually and reinstall.  and tell me
if that fixes it and what kind of system you are on.
