BTW, there is rarely a need to install Ghostscript explicitly.  On
Unix systems it's ubiquitous anyway, MacTeX provides Ghostscript, and
both, TeXLive and MikTeX provide a "hidden" (not in PATH) Ghostscript
for Windows.

TeX Live provides a script called "rungs" which invokes the hidden
Ghostscript on Windows or the gs binary in PATH on other platforms.
If you have TeX Live installed, simply run

  rungs -help

This should work on all platforms.  MiKTeX has a similar wrapper.
AFAIK it's called mgs.exe but I don't have Windows and can't check
myself.  But I suppose that under MiKTeX

  mgs -help

prints Ghostscript's help message to screen as well.

As far as AucTeX is concerned, it's probably worthwhile to check first
whether either rungs or mgs exist.  If not, check whether gs is in
PATH.  If everything fails, provide a reasonable error message.

IMO it's best to try to use in the first place what already exists.
