Sorry to say, its not convinient for me.

What is a typical python infrastructure if there such a thing? GNU Radio 
installs into <PREFIX><PYSITELIB>/gnuradio. Can you tell me how it differs 
from py-distutils?

I'm almost at the point to give up on pkgsrc. In many cases I find it much 
easier to take a third party package and install it into /usr/local 
filesystem as its done by most distros.

Its beyond a joke... :(
