solaris 10 编译安装PHP5时提示找不到freetype.h

在solaris 10 编译安装PHP5时提示找不到freetype.h，我的FREETYPE 是通过pkgutil 安装的.我的编译命令是
./configure --prefix=/usr/local/php5 --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/local/mysql5 --with-mysqli=/usr/local/mysql5/bin/mysql_config --with-libxml-dir=/opt/csw/bin --with-config-file-path=/etc/apache2 --with-gd=/opt/csw/bin --with-png-dir=/opt/csw/bin --with-freetype-dir=/opt/csw/bin --with-jpeg-dir=/opt/csw/bin --with-xpm-dir=/opt/csw/bin --with-zlib-dir=/opt/csw/bin --enable-gd-native-ttf --enable-gd-jis-conv --with-t1lib=/opt/csw/bin --enable-mbstring

我的freetype.h在

/opt/csw/include/freetype1/freetype/freetype.h
/opt/csw/include/freetype2/freetype/freetype.h
但是为什么是在编译的时候出现找不到呢。麻烦朋友帮我看一下到底问题出在那里。先谢谢大家了。

顶一下
