Update: While I can open and write to a file in the current (cgi) directory from within the program when running as a CGI, gpg as called from the CGI doesn't seem to write anything.
Aha. The directory containing the CGI scripts isn't even supposed to be world writable, or Apache will even refuse to run them. Create a separate directory (it looks like you already did), make it writable for everybody (chmod 777), and chdir to it in your CGI script before calling the external program.
