Description of problem:
NcFTP 3.2.0 from EPEL 4 can't be used with duplicity 0.5.06, please upgrade
at that branch minor - thank you.

From http://www.nongnu.org/duplicity/CHANGELOG:
> NcFTP version 3.2.0 will not work with duplicity since we require the
> use of both -f and -C options on ncftpput.  3.1.9, 3.2.1+ work fine.
> I put in error checks for this situation in the FTP backend code.

Version-Release number of selected component (if applicable):
ncftp-3.2.0-3.el4
duplicity-0.5.06-1

How reproducible:
Everytime, see above.

Actual results:
NcFTP 3.2.0 from EPEL 4 can't be used with duplicity 0.5.06.

Expected results:
NcFTP 3.2.1+ in EPEL 4 (I think we can bump it to 3.2.2 as in EPEL 5?).
