我正在尝试编译 PHP 5.2，因为我需要在新服务器上运行旧应用程序。我正在使用这个配置：
./configure --prefix=/opt --with-apxs2=/usr/bin/apxs2 --enable-soap --with-pear --with-pgsql --with-curl=/usr/bin --enable-bcmath --enable-ftp --with-mcrypt --with-mhash --with-pdo-mysql --with-pdo-pgsql --with-mssql=/usr/local/freetds --with-ttf=/usr/lib --with-t1lib --with-xpm-dir=/usr/lib --with-freetype-dir=/usr/include/freetype2 --with-gd --with-gettext --enable-mbstring --with-mm
运行该配置时没有错误，但是，一些日志消息显示它看到 FreeType ...？

即使指定了所有这些，我仍然只是得到
GD Support enabled
GD Version bundled (2.0.34 compatible)
GIF Read Support enabled
GIF Create Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled
这个应用程序来自的旧服务器在 phpinfo 的 GD 部分中有这个：
GD Support enabled
GD Version bundled (2.0.34 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.3.5
T1Lib Support enabled
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XPM Support enabled
XBM Support enabled
新服务器是 Ubuntu 13.04 服务器，我已libfreetype6安装。FreeType 未显示为已启用，我做错了什么？
