poudriere and conflicting packages

[Victor Sudakov]

Colleagues,

How do you use poudriere to build packages from conflicting ports?
E.g. I would like for both lang/php53-extensions and
lang/php5-extensions to be available in the repository. 

How does pkg.freebsd.org manage this?

Currently php53-extensions-1.6 does not build in the build-depends
phase. Not to clutter the list, I have put the build log to
http://gfile.ru/a4TuH 

TIA for any input.
