Fedora Users — Trying to Install Scorched Earth on Fedora

My wife's computer was running WinXP as of two days ago, until a virus got through the firewall and ripped it to shreds. Really. I don't have much control of what she does (under windows) but this is twice in under 4 months. So, I have moved her into the wonderful world of Linux. To help her overcome the perception that nothing "fun" runs under Linux, I am trying to install some games that she might enjoy. I am starting with Scorched Earth since I think that I might enjoy that one too. I certainly enjoyed the DOS version 10 years or so ago.

So, I am trying to install "Scorched Earth" on Fedora Core 1, and am having limited success. The game RPM can be found at http://scorched3d.sourceforge.net/downloads.php . When I try to install the RPM, I get a dependency failure because libwx_gtk-2.4.so.0 is required and not found. I did a google search and found what appeared to be the right thing at http://www2.linuxforum.net/RPM/libwx_gtk-2.4.so.0.html . I installed this RPM successfully, however it did not correct the error while installing the Scorched Earth RPM. So...

How do I found out what version of libwx_gtk I have, or if I even have it? Has anyone installed this successfully? And of course, how? Is installing programs not included in the distribution going to be as difficult as it seems? Why don't the RPM's simply include the required files?

Although off subject, I noticed that I can create shortcuts, but I can't drag them to other locations on the desktop. What's up with that? How do I manually arrange my desktop icons?
