Sure, I was just writing a post scriptum:
And in the latter case, you wouldn't even have to patch / modify the
spkg's / upstream's `setup.py`, but just `spkg-install` (or whatever that
will become), as you can also do things like
{{{
#!sh
python <<EOF
# Do some stuff, e.g. modifying distutils.file_util.*
# (preferably importing an alternate implementation located elsewhere)
import sys
sys.argv = ["setup.py", "install"]
execfile("setup.py")
EOF
}}}
Or just create a (shell) script that does similar, and call that instead
of doing `python setup.py install`.
