Since update-sourcecode was rewritten, rocketfuel-setup is very broken.
Things go like this:
1) rocketfuel-setup downloads lp:launchpad/devel.
2) rocketfuel-setup runs rocketfuel-get from devel.
3) rocketfuel-get downloads download-cache into lp-sourcedeps.
4) rocketfuel-get runs update-sourcecode.
5) rocketfuel-get runs link-external-sourcecode.
6) rocketfuel-get runs make.
Unfortunately, everything dies at step 4. update-sourcecode now depends on _pythonpath.py, which doesn't exist until make has run, which won't work until link-external-sourcecode has run, which won't work until update-sourcecode has run, which....
This sucks. It's now impossible to install Launchpad unless you really know what you're doing. link-external-sourcecode fortunately works just enough to unbreak 'make', so to fix a broken half-installation just run 'make' and 'rocketfuel-get' again.
To improve searchability, the error you get is:
Sourcedeps: /home/jtatum/
Traceback (most recent call last):
File "/home/
import _pythonpath
ImportError: No module named _pythonpath
To run make:
$ make -C ~/launchpad/
