The issue replicated in a minimal way (it's in the ticket too):

 dstromberg at zareason-limbo6000a /tmp/tt $ mv treap treap-dir

dstromberg at zareason-limbo6000a /tmp/tt $ /usr/local/cpython-3.3/bin/python
-c 'import sys; print(sys.path); import treap; t = treap.treap()'
['', '/usr/local/cpython-3.3/lib/python33.zip',
'/usr/local/cpython-3.3/lib/python3.3',
'/usr/local/cpython-3.3/lib/python3.3/plat-linux',
'/usr/local/cpython-3.3/lib/python3.3/lib-dynload',
'/usr/local/cpython-3.3/lib/python3.3/site-packages']

dstromberg at zareason-limbo6000a /tmp/tt $ mv treap-dir/ treap
