Cannot build launchpad on Fedora 10

I get launchpad trunk code and compile using make but failed with following error

rm -f -r lib/canonical/launchpad/apidoc lib/canonical/launchpad/apidoc.tmp
mkdir -p lib/canonical/launchpad/apidoc.tmp
LPCONFIG=development /home/hieu/launchpad/bin/py ./utilities/create-lp-wadl-and-apidoc.py \
     --force "lib/canonical/launchpad/apidoc.tmp/"
