I followed your link to Crazyinsomniacs repository and found that right below the SDL.gz file, there is a .ppd file.

SDL_Perl-2.1.0.tar.gz 139,279 16:27:42 20-Apr-2004

SDL_Perl.ppd [ C K ] 572 13:05:39 20-Apr-2004
[download]

However, I'm not sure that it will help as SDL_perl.dll has dependancy upon 6 other .dlls that do not appear in the .gz file. SDL_GFX.dll, SDL_IMAGE.dll, SDL_MIXER.dll, SDL_NET.dll, SDL_TTF.dll and SMPEG.dll.

I can only assume that these form some part of an independant package or more likely C-library, that you will need to locate, download and install on your system.

Having never used SDL, I can't help further. You'd best hope that CrazyInsomniac will step in here:0
