check if there's another version of librsync.so in your LD_LIBRARY_PATH
here some background info how native libs are found linux like systems. i guess 
freebsd counts as one.
http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html

my guess would be your /usr/local/lib/librsync.so is not used but the other one 
instead because it is found first.
