FreeBSD＋Apache＋PHP＋GD＋TTF求助

Helvin

安装顺利
GD Support  enabled  
GD Version  bundled (2.0.15 compatible)  
FreeType Support  enabled

GIF Read Support  enabled  
GIF Create Support  enabled

但是不能使用TTF，一个在Win下正常的PHP程序，放到FreeBSD下中文显示乱码

PHP为ports安装，freetype2 （听说支持TTF）对GD部分作了以下修改
CONFIGURE_ARGS+=--with-gd \
                --enable-gd-native-ttf \
                --enable-gd-imgstrttf \
                --enable-gd-jis-conv \
                --with-freetype-dir=${LOCALBASE} \
                --with-jpeg-dir=${LOCALBASE} \
                --with-png-dir=${LOCALBASE}
