Unfortunately, that's not it; I get:

gpg: WARNING: unsafe permissions on homedir `/opt/app/apps/dbmprod/gpg'
gpg: WARNING: using insecure memory!
gpg: please see http://www.gnupg.org/faq.html for more information
usage: gpg [options] --decrypt [filename]

Also, here is my setup:

bd9439 at dspsas01 $ gpg --homedir /opt/app/apps/dbmprod/gpg --version
gpg: WARNING: unsafe permissions on homedir `/opt/app/apps/dbmprod/gpg'

And yes, I know it's an old version.  I just have not had a reason to upgrade; what we have has worked fine (until now).  And yes, the "unsafe permissions" is understood.  I have this installed in a "public" directory so all users can decrypt files (we have a common key to receive files from outside sources).  This is the first time I've seen such a message.  We will ask the outside sourced to re-encrypt and re-send the file (perhaps it was corrupted during FTP), but I'm curious what this error message means.

Thanks!
