Re: [Duplicity-talk] Can't find _librsync?

[Scott Hannahs]

There were no complaints and the file is there.  Do I have the wrong 
PYTHONPATH?  Shouldn't it search the duplicity subdirectory?

% file /usr/local/lib/python2.6/site-packages/duplicity/_librsync.so 
/usr/local/lib/python2.6/site-packages/duplicity/_librsync.so: Mach-O universal 
binary with 3 architectures
/usr/local/lib/python2.6/site-packages/duplicity/_librsync.so (for architecture 
i386):  Mach-O bundle i386
/usr/local/lib/python2.6/site-packages/duplicity/_librsync.so (for architecture 
ppc7400):       Mach-O bundle ppc
/usr/local/lib/python2.6/site-packages/duplicity/_librsync.so (for architecture 
x86_64):        Mach-O 64-bit bundle x86_64

If I add both the site-packages and the duplicity folder explicitly then it 
finds the file _librsync.  But it then has an unresolved reference and still 
fails.  It can't find _rs_file_copy_cb

export 
PYTHONPATH=/usr/local/lib/python2.6/site-packages:/usr/local/lib/python2.6/site-packages/duplicity:/sw/lib

>>> import _librsync.so
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError:
