Hi,

No one not on karmic will be seeing this, since it's only on Karmic that
python-lazr-uri was packaged as a .deb, but something's broken with
buildout's isolation from system installed packages.


When attempting to set up a fresh launchpad development instance on
Karmic, if python-lazr-uri is installed, it dies like so:


Getting distribution for 'lazr.uri==1.0.1'.
Installing lazr.uri 1.0.1
Caused installation of a distribution:
lazr.uri 1.0
with a different version.
Got None.
While:
  Installing.
  Getting section filetemplates.
  Initializing part filetemplates.
Error: There is a version conflict.
We already have: lazr.uri 1.0
make: *** [/home/maxb/launchpad/lp-branches/stable/bin/py] Error 1



My first reaction was to "dpkg --force-depends --purge python-lazr-uri"
which produced this somewhat perplexing traceback:

ImportError: No module named uri
An error occured when trying to install lazr.uri 1.0.1. Look above this
message for any errors that were output by easy_install.

  Getting section filetemplates.

Error: Couldn't install: lazr.uri 1.0.1

Following on from which I also did "dpkg --force-depends --purge
python-lazr-restfulclient", upon which buildout successfully installed
lazr.uri 1.0.1 into the eggs directory.


Once the lazr.uri 1.0.1 egg was present in the eggs directory, it was
possible to reinstall the removed .debs without breaking the launchpad
tests.


Weird.
Any thoughts? :-)

Max.
