import paths for _intset from loader.py don't work on source install

[dan kuebrich]

Would get the following error when doing "from meliae import loader" in an interactive python shell:

Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from meliae import loader
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "meliae/loader.py", line 32, in <module>
    from meliae import (
ImportError: cannot import name _intset

Fixed it by adding this hacky line in loader.py before the bad import:

sys.path.append('/usr/local/lib/python2.6/dist-packages/meliae/')

I installed it by pulling down a 0.3.0 tarball (sdist on pypi currently broken) and running sudo python setup.py install . It installed to /usr/local/lib/python2.6/dist-packages/

Assuming I didn't do something wrong, there's a problem with the import paths.
