Issue #11054: Allow Mac OS X installer builds to again work on 10.5 with
the system-provided Python. Also, properly guard a new Python 3 only
installer build step so that build-installer.py can stay compatible
with the 2.7 version. (with release manager approval for 3.2rc2)

 1.  32-bit-only, i386 and PPC universal, capable on running on all machines
     supported by Mac OS X 10.3.9 through (at least) 10.6::
 
-        python2.6 build-installer.py \
+        python build-installer.py \
             --sdk-path=/Developer/SDKs/MacOSX10.4u.sdk \

             --dep-target=10.3 
         * ``MacOSX10.4u`` SDK (later SDKs do not support PPC G3 processors)
         * ``MACOSX_DEPLOYMENT_TARGET=10.3``
         * Apple ``gcc-4.0``
-        * Python 2.6 for documentation build with Sphinx
+        * Python 2.n (n >= 4) for documentation build with Sphinx
 
     - alternate build environments:
 
 
 2.  64-bit / 32-bit, x86_64 and i386 universal, for OS X 10.6 (and later)::
 
-        python2.6 build-installer.py \
+        python build-installer.py \
