error while loading shared libraries: libexif-gtk.so.4

Configuring, compiling and installing gtkam all seemed
to work fine:

$ ./configure --prefix=/usr/local
$ make
$ su -c "make install"

But trying to run it I get an error:

$ gtkam
gtkam: error while loading shared libraries:
libexif-gtk.so.4: cannot open shared object file: No
such file or directory

The library exists in a place where other programs can
find libraries:

$ find /usr -name libexif-gtk.so.4
/usr/local/lib/libexif-gtk.so.4

I'm running Red Hat 9 and needed the newer version as
the one supplied with the distribution didn't support
my Canon Powershot A80.

Any help would be appreciated.
