** Also affects: automake1.11 (Ubuntu Precise)
   Importance: Undecided
       Status: New

** Changed in: automake1.11 (Ubuntu Precise)
       Status: New => Triaged

** Changed in: automake1.11 (Ubuntu Precise)
   Importance: Undecided => Medium

** Description changed:

+ [Test Case]
+ You can reproduce it by attempting a 'make distcheck' in any automake based AM_PYTHON using package (e.g. subunit).
+ 
+ [Regression Potential]
+ This fixes bad code with more careful code, so potential is low. The test case described should be all that is necessary.
+ 
+ ------------------
+ 
  AM_PATH_PYTHON used to generate install logic like:
  if test -z "$(DESTDIR)"; then \
-    PYTHON=$(PYTHON) $(py_compile) --basedir "$(demodir)" $$dlist; \
+    PYTHON=$(PYTHON) $(py_compile) --basedir "$(demodir)" $$dlist; \
  else \
-   PYTHON=$(PYTHON) $(py_compile) --destdir "$(DESTDIR)" --basedir "$(demodir)" $$dlist; \
+   PYTHON=$(PYTHON) $(py_compile) --destdir "$(DESTDIR)" --basedir "$(demodir)" $$dlist; \
  fi; \
  
  Now however, it generates it without the test -z guard, which makes regular 'make install', and 'make distcheck' fail:
  make distcheck
  ....
  ../py-compile: Missing argument to --destdir.
