Yes, without problems. 

I now found out where the error comes from. The passphrase that Gnus
passes to gpg should be enclosed in '' to prevent any shell action on
it.

Try

~$ echo "hel$lo"

vs. 

~$ echo 'hel$lo'

Seen the problem? I found it out by trying 

~$ echo "Mypass$phrase" | gpg --status-fd 2 --passphrase-fd 0 \
 --output gpg.out --clearsign --armor --batch --verbose \
 --local-user frank@kuesterei.ch netenv.conf; echo $?

which should be exactly the call Gnus does. With echo 'Mypass$phrase' it
works. But I guess it's better to check with any character that's
allowed in passphrases. I checked that redirection signs are no problem.

Unfortunately, I do not dare to code this in Lisp, so I can't provide a
patch. 

Bye, Frank
