[gentoo-user] Given the rough end of the pineapple by liblzma.so.0

[Andrew Lowe <agl@wht.com.au>]

Hi all,
	I'm updating my machine and things were going well until something died 
and I got a big long list of reports. You know the ones, that emerge 
spits out after each package compiles and tells you to run 
etc-update/revdep-rebuild/gcc-config etc. Anyway, one of them was from:

	app-arch/xz-utils-5.0.1

telling me to run revdep-rebuild:

	# revdep-rebuild --library '/usr/lib64/liblzma.so.0'

and then delete liblzma

	# rm '/usr/lib64/liblzma.so.0'

Being a good boy, I did as I was told, ran revdep-rebuild then rm, had a 
bit of a fiddle round to try and fix the thing that caused the initial 
death and then kicked off the emerge world again. This is where the fun 
now begins. Now kdelibs-4.6.0-r1 can't find liblzma.so.0. The building 
of kdelibs now fails with:

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

I had a look in /usr/lib and found:

*********************

bluey lib # ls -la liblzma*.*
-rw-r--r-- 1 root root    911 Feb  6 22:14 liblzma.la
lrwxrwxrwx 1 root root     16 Feb  6 22:14 liblzma.so -> liblzma.so.5.0.1
lrwxrwxrwx 1 root root     16 Feb  6 22:14 liblzma.so.5 -> liblzma.so.5.0.1
-rwxr-xr-x 1 root root 141592 Feb  6 22:14 liblzma.so.5.0.1
bluey lib #

*********************

No .0, which, as you would remember from before, I've deleted. So what 
do I do now. I attempted to reinstall xz-utils but nothing changed. Do I 
need to install an old version of xz-utils? Do I just do a sym link from 
liblzma.so.5.0.1 to .0 and all will be well. Anyone got any ideas?

	Any thoughts greatly appreciated,
