 According to InstallDetails:

 {{{The "make install" target is a wrapper around "setup.py install" that
 uses --single-version-externally-managed to bypass the extra checking that
 setuptools does. This allows "make install" and "make install
 PREFIX=/usr/local" to work the same way as traditional unix software (via
 GNU autoconf, etc).}}}

 This entire sequence of commands succeeds:
 {{{
 $ python ./setup.py build
 $ python ./setup.py test # 0 unexpected errors
 $ mkdir /usr/local/stow/allmydata-tahoe-1.4.1
 $ make install PREFIX=/usr/local/stow/allmydata-tahoe-1.4.1/
 $ cd /usr/local/stow
 $ sudo stow allmydata-tahoe-1.4.1/
 # cd ~; which tahoe
 }}}

 The output of which shows /usr/local/bin/tahoe as expected.

 Yet some dependency or packaging issue is not configured correctly:

 {{{
 $ tahoe --help
 Traceback (most recent call last):
   File "/usr/local/bin/tahoe", line 5, in <module>
     from pkg_resources import load_entry_point
   File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 2562, in
 <module>
     working_set.require(__requires__)
   File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 626, in
 require
     needed = self.resolve(parse_requirements(requirements))
   File "/usr/lib/python2.6/dist-packages/pkg_resources.py", line 524, in
 resolve
     raise DistributionNotFound(req)  # XXX put more info here
 pkg_resources.DistributionNotFound: allmydata-tahoe==1.4.1
 }}}

 This ticket is satisfied when this use case succeeds and the
 InstallDetails documentation specifies the proper procedure.
