I tried your patch. But native-inputs are still there in the wrapped
PYTHONPATH. I printed out the results from various steps from the wrap
phase. They are as follows:

`build-time-inputs' is

`path' is

Somehow, the paths in `build-time-inputs' are not the same as those in
`path'. Notice the different hashes. Hence `remove' does not succeed in
filtering them out.

What is this part for?
