portmaster did not replace port

[Miroslav Lachman]

Hi,

I am trying to use portmaster to replace installed GnuPG 2 with GnuPG 1.
portmaster -o security/gnupg1 gnupg-2.0.4

But it always ends with gnupg-2.0.4 re-installed again, so now I have 
both versions installed. Is it possible to use portmaster for this task? 
(gnupg-2.0.4 was misinstalled by portmaster as dependency of 
p5-Mail-SpamAssassin-3.2.4_2, but SpamAssassin can be used with 
prevously installed gnupg-1.4.8)
