Ubuntu 12.10 included an updated version of fontconfig and as a result the intial release of Previous Releases will hang when attempting to start.and all
download again.for Linux has been updated so all you need to do is remove your existing install and
Second Life on 32bit Ubuntu 12.10
The following should work for most Second Life clients (including older versions of Catznip) on 32bit 12.10 Ubuntu and variants. (Based on write up and comments from http://freesoftwaredeveloper.blogspot.gr/2012/12/how-to-run-second-life-in.html)
This will NOT work on 64bit installs of Ubuntu 12.10, if in doubt open a console and type uname -a, if you see x86_64 anywhere on the line of output you are running 64bit.
sudo apt-get install libfreetype6-dev libfreetype6 libxml2 libxml2-dev libexpat1 libexpat1-dev
Download and extract font config.
cd wget http://www.freedesktop.org/software/fontconfig/release/fontconfig-2.8.0.tar.gz tar xvfz fontconfig-2.8.0.tar.gz cd fontconfig-2.8.0/
Compile and associated voodoo.
Change to the directory you extracted your Second Life client (this will be different for you!!).
Copy the font config files you just compiled.
cp ~/fontconfig-2.8.0/src/.libs/libfontconfig.so* ./
rm -r ~/fontconfig-2.8.0 rm ~/fontconfig-2.8.0.tar.gz
