I can build it just fine on Ubuntu dapper, but I can't run it.  The
command given in the comment fails immediately:

$ env LD_PRELOAD  dlibtest.so  ~/p3/python
env: LD_PRELOAD: No such file or directory
$

When I modify it slightly I get another error:

$ env LD_PRELOAD=dlibtest.so  ~/p3/python
ERROR: ld.so: object 'dlibtest.so' from LD_PRELOAD cannot be preloaded: ignored.
