compiled ghostscript successfully?


So I downloaded GS 6.51 from SourceForge, read all the docs, and compiled ghostscript. It looks like it compiled correctly (no compiling errors on screen). However, when I try to use the ps2pdf command it doesn't work...

[chris] %ps2pdfwr ./ ./alphabet.pdf
**** Unable to open the initial device, quitting.

I've also tried ps2pdf, ps2pdf13, etc. but they all give the same message. Ghostscript seems to be working ok since when I type gs I get the GS> promt. Any suggestions?????-- Cheers
