Building packages that need python pip to install certain python packages

[Willem Jan Withagen]

Hi,

I asked the question on the node installer, how to get things build
also packaged. And the actual answer was:
	you can't do that unless in the post-fetch() and then find
	a way to distribute to the correct places before the package
	starts building....
OR:
	give the user instructions what to do post installation.
	and have him do the work.

I haven't figured that on out yet.

Now I have a similar question for python packages that are not in the
ports tree, but do install and work with pip.

Is there a way to get a package dependancy on a
	'pip install <something>'
where the something atm is:
	pecan and ninja2

Thanx,
