Normally, you only need to recompile if there is a major version in
the library. If it is a minor version change, it is supposed to be
backward compatible. So if your program was compiled against
libfoo-1.2.1, and you upgrade to libfoo-1.2.5, it is supposed to
still work. Now a program compiled against libfoo-1.2.5 may not work
with libfoo-1.2.1.
