Re: [xsl] ImportError when importing etree from lxml

Scott, 

LibXslt is calling the version of libxml it was compiled against, which is not 
always the one installed on your system. When working with libraries you need 
to be careful with updates as they may break things like they did on your case.

To test try running 

xsltproc --version

Which should tell you the versions the different libraries were compiled against

My guess is that you'll have to upgrade libxslt so that it matches your 
installed version of libxml

Hello,

I am trying to run the python module lxml (in order to run python-docx).  I 
can import lxml okay, but whenever I try to import etree from lxml, I get an 
ImportError:

ImportError: /usr/lib/x86_64-linux-gnu/libxslt.so.1: symbol xmlBufUse, 
version   LIBXML2_2.9.0 not defined in file libxml2.so.2 with link time 
reference

Here is my configuration information:
- Python 2.7.6 running with Enthought Canopy.  
- Ubuntu 14.04 on VMWare Worstation 10.
- lxml 3.3.5
- libxml2 2.9.1+dfsg1-3ubuntu4
- libxslt1 1.1.28-2build1

It seems that the xslt library is calling for version 2.9.0 of libxml2, but 
I'm not sure why, because it appears that 2.9.1 has been out for a while.  I 
also cannot tell for sure whether this is a problem with lxml, libxslt, or 
libxml2.  I posted to the lxml list, and they didn't have any solutions, so I 
am now trying xslt.  

Any guidance or suggestions would be appreciated!  Thank you!
 
Thanks,
Scott
