The instructions in "Custom OpenSSL" section of "Using Python on Unix platforms" do not work on CentOS 7:

CPython's ./configure script assumes the OpenSSL's library resides in "$ssldir/lib". This isn't guaranteed with the current instruction, because OpenSSL might create for example lib64 for the .so files. See

> Some build targets have a multilib postfix set in the build configuration. For these targets the default libdir is lib<multilib-postfix>. Please use --libdir=lib to override the libdir if adding the postfix is undesirable.

Therefore it's better to explicitly set --libdir=lib.

The documentation was not up to date for OpenSSL 3.0.0. The default for --libdir was changed late in the development cycle.
