easy_install breaks due to SandboxViolation on SLES

I tried to install bzr on a SLES server using easy_install. I got this error:

mtafscbe1205cfs:/home/vandergar # easy_install bzr-2.2.2.tar.gz
/usr/lib64/python2.6/site-packages/setuptools/package_index.py:7: DeprecationWarning: the md5 module is deprecated; use hashlib instead
  from md5 import md5

No Pyrex, trying Cython...

The python package 'Pyrex' is not available. If the .c files are available,
they will be built, but modifying the .pyx files will not rebuild them.

The package setup script has attempted to modify files on your system
that are not within the EasyInstall build area, and has been aborted.

This package cannot be safely installed by EasyInstall, and may not
support alternate installation locations even if you run its setup
script by hand. Please inform the package's author and the EasyInstall
maintainers to find out if a fix or workaround is available.
