PHP 5.3.1 php-cgi missing from installation

I am attempting to install PHP 5.3.1 using CGI, but php-cgi seems to
have vanished in PHP 5.3.1. I've tried both the --enable-cgi and
--disable-cli flags for ./configure, but it doesn't create the php-cgi
binary under the sapi/cgi subdirectory. However, I was able to get
this working in PHP 5.3.0 just fine using the same exact procedure.

I am building from source on RHEL4 and used the following configuration:
./configure --prefix=/usr/local/php-5.3.1 --with-openssl --with-zlib
--enable-bcmath --with-bz2 --enable-calendar --with-curl --enable-exif
--enable-ftp --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr
--with-freetype-dir=/usr --enable-gd-native-ttf --with-gettext
--with-gmp --with-mhash --with-imap --with-kerberos --with-imap-ssl
--with-ldap --enable-mbstring --with-mcrypt --with-mysql
--with-mysql-sock=/var/lib/mysql/mysql.sock --with-mysqli
--enable-pcntl --with-pdo-mysql --with-pspell --enable-shmop
--enable-soap --enable-sockets --enable-sqlite-utf8 --enable-sysvmsg
--enable-sysvsem --enable-sysvshm --with-tidy --enable-wddx
--with-xmlrpc --with-xsl=/usr/local --enable-zip --with-pear
--with-libxml-dir=/usr/local --enable-cgi --disable-cli
