        <pre>Attempting to build util-errors using an out of tree build process fails as it
tries to run src/extensions.py from the build directory instead of the source
directory.

I assume it should be something like:

index 746cde3..08bcf7b 100644
--- a/Makefile.am
+++ b/Makefile.am
@@ -36,5 +36,5 @@ tests_test_LDADD = libxcb-errors.la $(XCB_LIBS)
 CLEANFILES = src/extensions.c

 src/extensions.c: src/extensions.py
-       $(AM_V_GEN)src/extensions.py $@.tmp ${XCBPROTO_XCBINCLUDEDIR}/*.xml &&
\
+       $(AM_V_GEN)$(srcdir)/src/extensions.py $@.tmp
${XCBPROTO_XCBINCLUDEDIR}/*.xml && \
        mv $@.tmp $@

Or better yet it configure search for python similar to how libxcb does and
then run something like:
$(AM_V_GEN)$(PYTHON) $(srcdir)/src/extensions.py</pre>
