+ The Python client README
(https://github.com/confluentinc/confluent-kafka-python) has an important note
for Kerberos case:
+ ```
+ **NOTE:** The pre-built Linux wheels do NOT contain SASL Kerberos
support.
+ If you need SASL Kerberos support you must install librdkafka
and
+ its dependencies using the above repositories and then build
+ confluent-kafka from source.
+ ```
+
+ so you will need to use the non-binary wheel to install
confluent-kafka-python and build/install librdkafka separately
+
1. Build Librdkafka with SASL support (` --enable-sasl`) and install at
your chosen $PREFIX.
```
- wget https://github.com/edenhill/librdkafka/archive/v0.9.4.tar.gz -O
- | tar -xz
- cd librdkafka-0.9.4/
+ wget https://github.com/edenhill/librdkafka/archive/v0.11.5.tar.gz -O
- | tar -xz
+ cd librdkafka-0.11.5/
./configure --prefix=$PREFIX --enable-sasl
make
make install
```
1. Validate Librdkafka does indeed support SASL. Run the following
command and ensure that `sasl` is returned as a built-in feature.
```
- $ examples/rdkafka_example -X builtin.features
- builtin.features = gzip,snappy,ssl,sasl,regex
- ```
-
- If it is not, ensure that you have `libsasl` or `libsasl2` installed.
On CentOS, this can be installed with the following command.
- ```
- yum install -y cyrus-sasl cyrus-sasl-devel cyrus-sasl-gssapi
+ $ examples/rdkafka_example -X builtin.features
+ builtin.features =
gzip,snappy,ssl,sasl,regex,lz4,sasl_gssapi,sasl_plain,sasl_scram,plugins
```
+1. The source install of confluent-kafka:
+
+ ```
+ // If you have already installed, remove the binary wheel python
client first, repeat until it says no longer installed

Can you extract the comment from the code block? Seems like it just just
