 librdkafka opportunistically uses lots of libraries.

 The binary built by our build server on which no extra libraries would be
 installed has the following linkage:

 {{{
 $ otool -L ./opt/local/lib/librdkafka.1.dylib
 ./opt/local/lib/librdkafka.1.dylib:
         /opt/local/lib/librdkafka.1.dylib (compatibility version 0.0.0,
 current version 0.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1252.50.4)
         /usr/lib/libsasl2.2.dylib (compatibility version 3.0.0, current
 version 3.15.0)
         /usr/lib/libz.1.dylib (compatibility version 1.0.0, current
 version 1.2.11)
 }}}

 In contrast, building it from source on my own computer which has many
 extra libraries installed had the following linkage:

 {{{
 $ otool -L ./opt/local/lib/librdkafka.1.dylib
 ./opt/local/lib/librdkafka.1.dylib:
         /opt/local/lib/librdkafka.1.dylib (compatibility version 0.0.0,
 current version 0.0.0)
         /opt/local/lib/liblz4.1.dylib (compatibility version 1.0.0,
 current version 1.9.2)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1252.50.4)
         /opt/local/lib/libzstd.1.dylib (compatibility version 1.0.0,
 current version 1.4.4)
         /opt/local/lib/libsasl2.3.dylib (compatibility version 4.0.0,
 current version 4.0.0)
         /opt/local/lib/libssl.1.1.dylib (compatibility version 1.1.0,
 current version 1.1.0)
         /opt/local/lib/libcrypto.1.1.dylib (compatibility version 1.1.0,
 current version 1.1.0)
         /opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current
 version 1.2.11)
 }}}

 As you can see there are lots of MacPorts libraries that librdkafka will
 link with if they exist. For each such library, one of two fixes could be
 employed: either add the dependency on the corresponding MacPorts port or
 tell the build system not to use that library even if it is present. And
 then the revision would need to be increased.
