allmydata.PackagingError:
PackagingError: We require pycryptopp >= 0.5.20, but could only find version
0.5.17.
The version we found is from '/usr/lib/pymodules/python2.7'.
To resolve this problem, uninstall that version, either using your
operating system's package manager or by moving aside the directory.
For debugging purposes, the PYTHONPATH was
None
install_requires was

Description: Secure distributed filesystem
Tahoe, the Least Authority File System, is a distributed filesystem that
features high reliability, strong security properties, and a fine-grained
sharing model. Files are encrypted, signed, erasure-coded, then distributed
over multiple servers, such that any (configurable) subset of the servers
will be sufficient to recover the data. The default 3-of-10 configuration
tolerates up to 7 server failures before data becomes unrecoverable.
.
Tahoe offers "provider-independent security": the confidentiality and
integrity of your data do not depend upon the behavior of the servers. The
use of erasure-coding means that reliability and availability depend only
upon a subset of the servers.
.
Tahoe files are accessed through a RESTful web API, a human-oriented web
server interface, and CLI tools.

Here I cutnpaste the different dependencies for clarity:
tahoe-lafs: ['setuptools >= 0.6c6', 'zfec >= 1.1.0', 'simplejson >= 1.4',
'zope.interface', 'Twisted >= 2.4.0', 'foolscap[secure_connections] >= 0.6.1',
'Nevow >= 0.6.0', 'pycrypto == 2.0.1, == 2.1.0, >= 2.3', 'pyasn1 >= 0.0.8a',
'mock', 'pycryptopp >= 0.5.20']
apt-cache: Depends: python (>= 2.5), python-support (>= 0.90.0),
python-twisted, python-foolscap (>= 0.4.1), python-openssl, python-nevow,
python-simplejson (>= 1.4), python-zfec (>= 1.1), python-pycryptopp (>=
0.5.14), python-setuptools
Note: missing dependency on mock is already filed in this bug:
https://bugs.launchpad.net/ubuntu/+source/tahoe-lafs/+bug/782379
maybe the two bugs should be merged
