   4 Subject: [PATCH] Fix building on Nix
   5
   6 ./configure.py tries to find dbus-python header in dbus-1 includedir
   7 obtained from pkg-config or from --dbus flag. Unfortunately, when supplied,
   8 it also uses the flag for locating dbus-1 headers. This fails on Nix,
   9 since every package is installed into its own immutable tree so we cannot
  10 use a single directory for both dbus-python and dbus-1. We can fix this by
  11 using pkg-config for finding dbus-python headers too.
  12
  13 Additionally, the build system also tries to install the dbus support module
  14 to dbus-python tree. Often, it is possible to handle this in pkgconfig as well [1]
  15 but unfortunately, dbus-python does not export the moduledir in its pc file
  16 so I have decided to solve this with an extra configure flag.
