Re: [PATCH v7] Add hplip

[Ludovic Courtès]

Hi,

Here’s an improved version of the patch you posted, which removes the
dependency on Autoconf/Automake and keeps using /var as the
localstatedir.

However, programs now need help to find their Python modules:

 line 33, in <module>
    import cupsext
ImportError: No module named 'cupsext'
--8<---------------cut here---------------end--------------->8---

Could someone add a phase to do this?

TIA.  :-)
