root port file python support

[Mattia Francesco Moro]

Hi, to all! This is my first mail in dev mailing list.
I have a problem with this portfile: http://trac.macports.org/ticket/23856

i need to pass on the output of:

python-config --includes | sed -e 's/-I//' | awk '{print \$1}'

to configure script. I try in this way:

http://trac.macports.org/attachment/ticket/23856/Portfile#L121

but it doesn't work. Any idea?

Mattia
