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