bzr: ERROR: Unable to import library "fastimport": No module named fastimport

[Oliver Schrenk]

I'm trying to convert a bzr repository into a git repository

Using OS X 10.6.5

	brew install bazaar
	mkdir -p ~/.bazaar/plugins
	cd ~/.bazaar/plugins
	bzr clone lp:bzr-fastimport fastimport
	
	mkdir ~/project.git
	cd ~/project.git
	git init
	bzr fast-export --plain ~/path/to/bzr/branch | git fast-import

When running the last command I get 
	
	bzr: ERROR: Unable to import library "fastimport": No module named fastimport

I must be missing something obvious. 

Best regards
