there was a similar issue once on Mac OSX, where it was compiled against x64 but run x86 or the other way around. see

you might want to further dig into our mailing list.

good luck.. ede/duply.net

thanks for you reply,

i have found this before and at last it given no solution and i reinstalled the librsync,

but the same error occurs .

Both the duplicity and librsync are installed by sourcecode on vmware8.0 FreeBSD.

which explains there is no confusing about the hardware type.

Actually being part of that thread, there was a resolution if you look at the entire thread in the archive.

But the problem is mixing python, gnupg, librsync and duplicity.  All must either be 32 or 64bit compiled.  Use the "file" commands on the various executables and libraries to make sure that they are all compatible.  What are the code types for each of these?

Make sure that PYTHONPATH is sending you to the right version of the libraries and not an older incompatible version.
