In Python 3, you can use ${base_dir}/bin, and the extended interpolation allows you to use variables from other sections. Example:

macports_dir: /opt/local

[Frameworks]
Python: 3.2
path: ${Common:system_dir}/Library/Frameworks/

my_pictures: ${my_dir}/Pictures
python_dir: ${Frameworks:path}/Python/Versions/${Frameworks:Python}
