You can specify the python module path by setting the environment variable named PYTHONPATH. You can install the different versions in different directories, and change the value of this variable each time you want to switch versions. This can also be automated using the virtualenv package: http://www.virtualenv.org Just google PYTHONPATH and/or virtualenv and you will find all sorts of guides/howtos. > - change the library name, so I could do something like "import graph_tool" > to get the official version and "import graph_tool_mydevel" to get my > modified version This wont work, since the module refers to itself internally at some places by its standard name... You would have to change all theses references as well. Cheers, Tiago -- Tiago de Paula Peixoto <[email protected]>
