| Yes, this would be the preferable situation, but it is not completely
| under our control, because the python version checks are done in
| macro AM_PATH_PYTHON, included in aclocal.m4 by the aclocal command.=20

| There is a workaround, though, by redefining temporarily the
| AC_MSG_ERROR macro around the call to AM_PATH_PYTHON.  The m4 trick

|
|     pushdef([AC_MSG_ERROR],defn([AC_MSG_WARN]))
|     AM_PATH_PYTHON(1.5)
|     popdef([AC_MSG_ERROR])
|
| Then, instead of stopping when python is not available, configure
| continues but barks like this:
|
|     [...]
|     checking for sin in -lm... yes
|     checking for a Python interpreter with version >=3D 1.5...
| configure: WARNING: no suitable Python interpreter found

| What do you think?  Should I commit this change?

I think it's better, although it's not nice.
Perhaps changing the message to=20

       configure: WARNING: no suitable Python interpreter found, please
        ignore the next  6 messages

?
