Could you elaborate on this for a Linux newbie please? I carried out step 1 with no problems, but when I view /etc/ld.so.conf, I get the following:

    $ cat /etc/ld.so.conf
    include ld.so.conf.d/*.conf

I don't know how to use ld - I see from the man pag that it's used for linking files, but I don't know (in this context) what files I want to be linking to what.

I've copied libpython2.7.so and libpython2.7.so.1.0 to the folder in $LD_LIBRARY_PATH, meaning I don't get the problems detailed in the original post anymore, but I'm concerned that I'm sticking a plaster over a bigger problem.
