ghostscript agpl and texlive

[Konstantin Belousov]

Hi,
I am trying to update ports on my workstation (using portupgrade) due to
TexLive 2015 import, and there I am stumbled.  I run stable/10 amd64,
I have ghostscript9-agpl-9.16_1 installed.  An attempt to run
	 portupgrade -f ja-tex-ptex-3.5 tex-\* texlive-\*
fails because
===>   texlive-base-20150521_1 depends on file: ghostscript9>=0 - not found
===>  Installing for ghostscript9-9.06_10
...
===>  Checking if ghostscript9 already installed
===>   Registering installation for ghostscript9-9.06_10 as automatic
Installing ghostscript9-9.06_10...
pkg-static: ghostscript9-9.06_10 conflicts with ghostscript9-agpl-9.16_1 (installs files into the same place).  Problematic file: /usr/local/bin/dvipdf

I do not see how to specify that I need ghostscript 9 agpl by using the
DEFAULT_VERSIONS stuff.  If so, this would be even more problematic if
building with poudriere.

Any hints ?  Thank you in advance.
