OK, if I pop up Synaptic I find lots of entries for svga. (But none for the strange application you're trying to install or I'd suggest you did an apt-get for it, rather than pratting about with source code ).

For example:

svgalib-bin (which carries a "use with caution" flag)
libsvga1 (which is included in Knoppix)
libsvga1-dev

My guess (nothing more) is that the first or the third are what's required. Put them on and give it a try.

You want to su to root, do

apt-get update && apt-get install svgalib-bin libsvga1-dev && exit

then try your compile again. It's unfortunate thaty many developers simply don't state the "precise" names of dependencies (but, then, often they have different names in different distros. Often it'll be the development libraries of something you already have.
