as it would have indicated during the install of libsndfile, you need
to either:

   set LD_LIBRARY_PATH to include wherever the library is located OR
   edit /etc/ld.so.config to contain the directory where the library
      is located, and then run ldconfig (as root)

shared libraries are found by using a combination of LD_LIBRARY_PATH
and the ld.so.config file. if a library cannot be found that way
(though strictly, there are a couple of other (bad) options), then you
get the error you've encountered.
