Error with Pacman

Question

Yesterday I tried to do an upgrade of my system via pacman -Syu and I was told to update pacman (and about two other things which I can't remember what they were) and now I am getting the following error when I try to run pacman -Syu again:
arch linux - pacman:error while loading shared libraries: liblzma.so.5: cannot open shared object file: No such file or directory
I found a thread which has a number of fixes but I am unsure which one I should use. The thread is here:
https://bbs.archlinux.org/viewtopic.php?id=77382
So I am unsure how to solve this. I would appreciate help on fixing this as I am still a beginner.
Thanks in advance.

Remembering that symlinking libraries is really bad...
ln -s /usr/lib/liblzma.so.0 /usr/lib/liblzma.so.5
pacman -Sf xz
pacman -Syu
Should get your system back going...
Okay I did the above but I got the following errors:
[root@media ~]# ln -s /usr/lib/liblzma.so.0 /usr/lib/liblzma.so.5
[root@media ~]# pacman -Sf xz

then when I did pacman -Syu I got the following:
