CentOS 5 :: Cannot Compile PHP With GD JPEG Support

I've successfully compiled and installed PHP to run with nginx. But I could not use some jpeg functions from GD library. I've checked for libjpeg-devel and gd-devel and found that they had been installed, libjpeg.so is located at /usr/lib This is my configure command:

./configure --with-config-file-path=/etc/php --with-config-file-scan-dir=/etc/php/conf.d --disable-pdo --with-openssl --with-pcre-regex --without-sqlite3 --with-zlib --enable-bcmath --with-bz2 --enable-calendar --with-curl --with-curlwrappers --enable-exif --with-gd --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --with-freetype-dir=/usr/lib --enable-gd-native-ttf --enable-gd-jis-conv --with-gettext --with-mhash --enable-intl --enable-mbstring --with-mcrypt --with-mysql --with-mysql-sock --enable-soap --enable-sockets --with-xsl --enable-zip

phpinfo() shows that gd is enabled with GIF and PNG supports but without JPEG.
