OR perhaps configure can not file libsndfile, in which you can try 1 of 3 things:
1) set the environment variable PKG_CONFIG_PATH
to find the package file for libsndfile for example:
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
2) re-install libsndfile in /usr instead of /usr/local, where it installs by default.
3) There are some packages for libsndfile now, be sure to install libsndfile-devel
