myDSL Extensions (deprecated) :: SDL or SVGALIB DSL extension?
you'll want to install the dsl-dpkg.dsl extension, and maybe gnu-utils (not sure about that one).
Then go to where you download your deb files and do this command:
sudo dpkg -i name_of_file.deb
Can't say that'll work for everything...SDL-dev may need additional support files.
You could also try apt-get instead of dpkg (I think they are both in the same package?), which many people prefer...i can't verify either one personally, but i always like to have archives saved for future use rather than just download and run from a temp directory.
Thanks for the help Mike - I discovered Izarc for windows opens deb packages, so I was able to snag the headers out of it, and ftp over to my linux box. Not a proper SDL install, but the headers with the library and it actually works. It'll do. Something I've grown accustom to as far as linux goes. A lot of brute forcing; at least for me so far!
I only booted linux for the first time a few months ago because I was put on a programming project that my boss wants done in Linux! Great opportunity to learn linux. And man have I learned a crapload.. DSL is the best distribution I think... I've tried many. VNC works great with it too.. I dev on my linux box 100% via vnc from my windows box. There's no latency over the local network whatsoever! 
thanks!
