Ok, I have a plan. I'm going to close this thread as [SOLVED] as I got the help I needed to get past the initial GTK+ problem, with my thanks to all who helped. I now have a whole different issue
or as I like to think of it, an opportunity to learn.
If inquiring minds want to know my next steps, should you have the misfortune to find yourself in the same situation I'm now in where two packages have a conflict, I'm going to take this up on the packaging forum. I figure I have to learn to package sometime and I figure my resolution might be to run a patch on one of the conflicting packages and rebuild it into an rpm.
To be honest, running a patch and repackage is the 'lazy' way out - it's not going to directly benefit the community (as I'd fear for the safety of your systems if I was to make my first attempt public, but the desperate will be welcome to ask me for the new rpm if I find it doesn't trash my system
), but it's the easiest way for me to get into packaging, as I can basically grab the existing spec file (if I read the packaging tutorial right) and make some minor tweaks to it to accommodate the patch I'm applying to a package source and rebuild.
So, wxWidgets gets a patch. It'll be a variation of wxWidgets-2.8.10 with a patch applied to ensure glibc doesn't fight with it over the declaration of GSocket.
I'll try testing myself for as long as I can. I have zero idea of formal testing regimens for new or altered packages in a Linux environment, but I'll do what I can. I work in software QA in my day job these days so I at least have a plan there. (I program in C/C++, assembler and stuff as well, among other stuff)
This is what I like about Linux. If something doesn't work on Windows, you're basically hosed. Here, you can toss out a few thoughts, ask for help and you have the tools to try and help yourself and there's always the possibility you can do good for your fellow users, rather than some software house.
Of course, if I'm going about this the wrong way, somebody stop me....it's not like I'll get offended.
