Edgar,

Thanks for the response.

sap = scp (damn autocorrect)

Does the current backend for scp/sftp function with python 3.7?  If so did 
someone edit it to work around this lack of unmaintained pycryptopp already, 
and just not put it in the notes?

Is there somewhere a list of the minimal set of top level additional python 
modules needed to build duplicity and each of the backends?

I found the reference in the “README" file.  Possibly this is in error?  It 
lists both paramiko and pycryptopp.   I am really only interested in the top 
level needed libraries since I can work our dependencies automatically.  I 
thought that the scp/sftp backend needed it directly.  If it only needs 
paramiko then I can drop the requirement entirely.

"for scp/sftp -- python-paramiko and python-pycryptopp"

For reference, I am building a fink package for OS X.
