Comment (by yawning):

 I wrote a working `Crypto.Util.Counter` replacement, but it turns out that
 pycrypto 2.0.1's CTR mode only supports processing data that's a multiple
 of the block cipher's block size.

 This was fixed in pycrypto 2.1.0alpha2:
 {{{
         - Block ciphers created with MODE_CTR can now operate on strings
 of
           any size, rather than just multiples of the underlying cipher's
           block size.
 }}}

 Since `Crypto.Util.Counter` was added in 2.1.0alpha1, any version of
 pycrypto that has a non-brain damaged CTR-AES128 implementation will have
 the utility module in question.

 Unless anyone has any objections, I will close this as invalid since
 obfsproxy does indeed work with the system provided python and most of the
 dependencies.
