Yes, that is the way poudriere is designed. I will not write detailed 
instruction, just outline points. Poudriere repository is added to 
/usr/local/etc/pkg/ropes/poudriere.con, and pkg queries that first, then 
main pkg repository. Poudriere builds all packages that the one you need 
with your own config depends on, so the will be added from poudriere 
repo. When package that is not in poudriere repo is installed, it comes 
from main repo, dependencies to be installed first queried poudriere, 
then main repo. The only thing I can see may cause trouble is if you 
switched OFF some settings for dependency pkg in poudriere, if you only 
added enabled options, the package coming from poudriere should be good 
as dependency for pkg installed from main repo.

I have never had problem like that. At some point dependency in main 
repo might change by pkg maintainer. E.g. openldap-client is replaced 
with openldap-sasl-client. Then you will have to make sure the poudriere 
repo requires the same dependency from that point on.

True, but I can not see how it can be different. Note, that you are 
replacing a portion of (central) pkg build infrastructure. And it is 
still time saving comparing to building from ports. You can use 
poudriere built pkgs on multiple systems. Update using pkgs is faster, 
helping you with maintenance window for a machine.

I gave general view above (not trying to make it an instruction).

If I am wrong about something, I hope, experts will correct me.
