firefox 3 (xulrunner) 需要apng支持的libpng，怎么解决？

configure脚本检查一个库是否存在的原理：
一般就是弄个小程序编译一下连接一下
如果连接不通过，就认为该库不存在
这个小程序可以在log里找到
有时把它截取出来，自己单独编译一下，就可以找到问题所在

给libpng打了个patch，结果png过了，现在出现了这个问题了
checking for jpeg_destroy_compress in -ljpeg... yes
checking for gzread in -lz... yes
checking for BZ2_bzread in -lbz2... yes
checking for png_get_valid in -lpng... yes

我看到你在 Gentoo 官方论坛的帖子了，上面也说了不要打开 APNG，同时将 xulrunner 的 PNG 支持关闭。

现在的问题是我的配置好像出了问题，xulrunner在configure的时候不应该查找System-png的，但是在我这里总是要查找system-png。

xulrunner自带的png是满足apng扩展的，所以不知道为什么configure脚本总是要去搜索系统库。

估计是USE设置的问题。USE设置的太多了。

我用的就是glibc-2.8和gcc-4.3.1，USE="xulrunner" emerge firefox-3, 编译过程没有问题，libpng也是1.2.27
