+Subject: [PATCH] Workaround finding libudev on systems without ldconf
+
+This patch tries to load libudev.so directly without relying on
+Python's find_library(). find_library() fails on systems
+without library cache mechanism.
+
+Taken from pyudev issue 117 discussion:
+https://github.com/pyudev/pyudev/pull/117
