> Currently, we use {{dlopen}} to open {{libz.so}} and {{libsnappy.so}}, to get Gzip and Snappy support, respectively.
> However, this is not correct; we should be dlopening {{libsnappy.so.1}} instead. The versionless form of the shared library is not commonly installed except by development packages. Also, we may run into subtle compatibility problems if a new version of libsnappy comes out.
> Thanks to Brandon Vargo for reporting this bug.
