QuickBooks Linux DB Server Manager on my ReadyNAS?

Short version: Anyone have words of wisdom on running the QuickBooks Linux DB Server Manager on ReadyNAS OS6?

Longer version: I currently have both a Pro2 and a Pro6. The Pro2 came with OS6 (running 6.5.2 but I do plan to upgrade it to 6.6.1 eventually) and the Pro6 has been upgraded manually to 6.6.1 from the original Legacy Firmware. I also have a PC that I ONLY keep around because it runs the QuickBooks server for a business we acquired. IE we need to be able to get into it for historical stuff often enough that single user mode isn't sufficient.

The documentation for the QB Mgr says that I need to be running the following (or newer) things that are not already installed:

   gamin 0.1.7.7 OR fam 2.7.0

   libgcc 4.2.1

   libstdc++ 4.2.1

I assume I can install those via apt-get at the command line but are those known to break anything else or screw me up somehow (thinking especially future firmware upgrades)?

Any words of wisdom would be appreciated! Thanks!
