bzr fails to install

[mmu_man]

Maybe it's my dev image that is a bit outdated...
bzr fails to install here.
First, launchpad.net has a self-signed cert (must force wget in haikuporter).
Then :

running install_scripts
creating boot/common/bin
copying build/scripts-2.6/bzr -> boot/common/bin
changing mode of boot/common/bin/bzr to 755
running install_data
creating boot/common/man
creating boot/common/man/man1
copying bzr.1 -> boot/common/man/man1
creating /usr
creating /usr/share
creating /usr/share/apport
creating /usr/share/apport/package-hooks
copying apport/source_bzr.py -> /usr/share/apport/package-hooks
error: /usr/share/apport/package-hooks/source_bzr.py: invalid mode ('wb') or filename
