Google helps those who help themselves:
http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=pngalpha
The very first entry in the list of search results is:
"[gs-cvs] gs/src
... bcwin32.mak devs.mak gdevpng.c gdevprn.h macosx.mak msvc32.mak
openvms.mak os2.mak

I clicked on it. Here's two salient details from that page:
#1) "Log Message:
Add pngalpha device that uses RGBA, with the alpha channel
providing pixel coverage. Used for generating PNG images with a
transparent background. "
#2) "Tue Mar 11 03:36:44 PST 2003 "
Here's one salient detail from your earlier post:
#3) "> $ gs -version
> GNU Ghostscript 7.05 (2002-04-22)"
Any further questions?
[ There's really no earthly reason you shouldn't have been able to work
this out for yourself. I don't even use gs and haven't looked at it in four
or five years, but it only took me ten seconds to figure out what was wrong.
