distutils recipes is not using correctly install-from-cache setting
distutils recipe is getting self.install_
in line 110 the "if install_from_cache" is always true, because is never is an empty string. I don't know if it's posible to get the python boolean (not the string) for the settings, but if it's not posible the correct if statement is "if install_from_cache != 'false'"
I attach a patch file, but not sure about the format of the diff. This is the command I have used for generating the diff:
diff -u collective.
