升级系统时pango无法编译

由于libexpat已经被升级，libexpat.so.0变为libexpat.so.1，但pango编译时仍去找libexpat.so.0，导致编译出错。不知如何解决呢？

/var/tmp/portage/x11-libs/pango-1.16.5/work/pango-1.16.5/pango/.libs/lt-pango-querymodules: error while loading shared libraries: libexpat.so.0: cannot open shared object file: No such file or directory

试试 revdep-rebuild

error while loading shared libraries: libexpat.so.0: cannot open shared object file: No such file or directory

最近遇到libexpat.so的问题挺多的，搜一下老贴子吧，记得在官方论坛有个很好的解决方案

权宜之计是
cd /usr/lib/
ln -s libexpat.so.1 libexpat.so.0

如果觉得这样不放心
revdep-rebuild -X --library libexpat.so.0

我就是用了和meteo相同的办法继续编译的。
revdep-rebuild没有成功，有一个包有问题。现在正在升级，升级后再revdep-rebuild的方法试试吧。
