Then it's possible that don't have pkg-config installed and didn't notice the 
errors during configure (if I remember correctly this does not cause configure 
to fail, just print an error and continue). Install it so that pkg-config 
binary is in $PATH when you run configure and make sure that PKG_CONFIG_PATH 
contains the directory where hfst.pc is installed.

This is yet another thing to check for in the configure script and mention in 
the documentation... although this is only needed with the experimental 
backends.

If this does not help, check whether config.h (created as a result of running 
configure) contains the line

  #define HAVE_HFST 1
