SDL, prboom and aalib

[joebosak@uku.co.uk]

I am trying to run prboom under woody.  I have libsdl loaded, as required, 
and this in turn requires aalib.  Also got svgalib installed. 

Argh!  Prboom runs in text mode - ie. aalib. 

So I have a script that goes: 

SDL_VIDEODRIVER='svgalib' ; export SDL_VIDEODRIVER 

but that makes no difference. 

Any idea what to do?
