gentoo libexif.so.12 problem

[John Russell <jjrussell gmail com>]

While trying the 0.1.3 release of f-spot I ran in to the problem
described in this post.

http://mail.gnome.org/archives/f-spot-list/2005-October/msg00039.html

missing libexif.so.12.

The post acknowledges the problem, however, is there a way to make
this work on Gentoo?  Thanks for the help.
