pacman: error while loading shared libraries: libl

今天升级系统，老出现/tmp/alpm_whfxNY/.INSTALL: line 5: echo: write error: Broken pipe，就中断了，结果再升级就出现如下错误：

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

1. Download xz-utils from 
2. Extract tarfile
  $ tar xvf xz-4.999.8beta.tar.gz
3. Build
  $ cd xz-4.999.8beta
  $ ./configure && make
4. Install
  $ sudo make install
5. Reconfigure dynamic linker bindings
  $ sudo ldconfig /usr/local/lib

Now pacman should work again. Install xz-utils using pacman:
  $ sudo pacman -S core/xz-utils

Now you can uninstall the manually installed xz-utils by vising its source directory and:
  $ sudo make uninstall

Source directory and the downloaded tarfile can now be removed and everything should be in order.

edit: Just to be safe, do another pacman -S core/xz-utils after removing the manually installed packet.
