Typically there's a symbolic link on the system "libssl.so" (note no version) which points to whichever major version you want to use as the default. This "un-versioned" .so is what's used by the compile-time linker to determine which .so to link. Look for libssl.so and see if it points to libssl.so.4 or libssl.so.6.
