I'm going to attempt This: http://alien.slackbook.org/dokuwiki/doku.php?id=slackware:multilib#obtaining_multilib_packages
This article contains instructions on how to create a true multilib Slackware64. A multilib 64bit Linux system is capable of running 64bit as well as 32bit software. The Filesystem Hierarchy Standard dictates the best way to achieve a clean separation between 64bit and 32bit software on a single system. With Slackware64 we chose to adopt this standard, so it has been prepared to look for 64bit libraries in /lib64 and /usr/lib64 directories. This is why I call Slackware64 “multilib-ready” - even though 32bit libraries will be looked for in /lib and /usr/lib, Slackware64 does not ship with any 32bit software.
I know VLocity is slackware based but don't know how close it is to this Slackware64 version. I have tried other Second Life viewer clients, (which is what Firestorm is.. a client for the online game Second Life) on Mint 64 and they all return the same errors. Even installing multilib /multiarch libraries in Mint doesn't help and the best thinkers over there have no clue on how to proceed. I'd use another viewer if i could find one made for 64 bit slackware but it doesn't seem like anyone's made one. This might be my best option. Wish me luck.
