Versions of MySQL Connector/C may have incorrect default configuration options that cause compilation errors when `mysqlclient-python` is installed. (As of November 2017, this is known to be true for homebrew's `mysql-connector-c` and [official package](https://dev.mysql.com/downloads/connector/c/))
Modification of `mysql_config` resolves these issues as follows.
Change
```
# on macOS, on or about line 112:
# Create options
libs="-L$pkglibdir"
libs="$libs -l "
```
to
```
# Create options
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"
```
An improper ssl configuration may also create issues; see, e.g, `brew info openssl` for details on macOS.
