You need to build pdal with Python support too, and the python version 
for PDAL must be the same as for its Python bindings.

Don't mix the pdal & python-pdal packages with your self compiled one.

To fix the link issue you need to have PDAL compiled with Python 
support, and the PDAL libraries must be in the library search path. 
(/usr/local/lib should be included by default).
