One quick hack is to install the new numpy somewhere else and then
rename the directory containing 0.9.8 to numpySTOP. Then you don't
have to worry about the ordering of the path.

I install in /usr/local/scipy/numpy (then it is easy to remove numpy
without worrying about leaving behind any files) and then I create the
file /usr/lib/python2.4/site-packages/addlocalpath.pth that contains
the lines:


Then there is no need to play with the path.
