在wordpress上安装插件NextGEN Gallery 用于支持相册，在上传图片后出现错误
You do not have the GD Library installed. This class requires the GD library to function properly. visit http://us2.php.net/manual/en/ref.image.php for more information
根据网上检索，了解到php需要支持gb库用于图象生成，
所以对php重新进行编译，在configure里加上?with-gd，报错
configure: error: libpng.(a|so) not found
使用?with-png-dir=/usr/lib，依然出错。
使用yum install pnglib后，然后重新编译php，还是出错。
最后尝试使用yum install pnglib-devel，然后重新编译php，正常
原来php使用的是pnglib-devel而不是pnglib
