在 redhat 5 上建構 Python 3.2.3：缺少 _posixsubprocess

我正在嘗試在 RHEL 5.7 機器上建構 Python3，我成功地建構了 Python 3.2.2，其中：

# Install required build dependencies
yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

# Fetch and extract source. Please refer to http://www.python.org/download/releases
# to ensure the latest source is used.
wget http://www.python.org/ftp/python/3.2/Python-3.2.tar.bz2
tar -xjf Python-3.2.tar.bz2
cd Python-3.2

# Configure the build with a prefix (install dir) of /opt/python3, compile, and install.
./configure --prefix=/opt/python3
make

但我在 Python 3.2.3 上失敗了（？）：

Failed to build these modules:
_posixsubprocess     

這是一個應該困擾我的問題嗎？我該如何建構它？我找到了這個更新檔，但它沒有包含在我從網站獲得的 Python 3.2.3 原始碼中……

這是標準錯誤的輸出：

好的……我在這裡回答，而不是讓問題懸而未決。我重新下載了 Python-3.2.3 源並檢查了它們。他們確實不包括那個更新檔。

我重新應用了更新檔並在 CentOS-5.7 和 RedHat-5.7 上測試了該建構。我設法編譯沒有錯誤。

所以，我想關鍵是正確應用更新檔。我的失敗建構在 Modules/_posixsubprocess 中：

199 static void
200 _close_open_fd_range_safe(int start_fd, int end_fd, PyObject* py_fds_to_keep)
201 {
202     int fd_dir_fd;
203     if (start_fd >= end_fd)
204         return;
205         fd_dir_fd = open(FD_DIR, O_RDONLY | O_CLOEXEC, 0);
206 #ifdef O_CLOEXEC
207      fd_dir_fd = open(FD_DIR, O_RDONLY | O_CLOEXEC, 0);
208 #else
209     fd_dir_fd = open(FD_DIR, O_RDONLY, 0);
210 #ifdef FD_CLOEXEC

第 205 行，應該已經刪除…
