Comment 8 for bug 377584

simple configure.ac, but any configure.ac using AM_PATH_PYTHON() is enough
AC_INIT()
AM_PATH_PYTHON()
AC_CONFIG_FILES(foo.in)
AC_OUTPUT

output in jaunty:
$ ./configure
checking for python... /usr/bin/python
checking for python version... 2.6
checking for python platform... linux2
checking for python script directory... /usr/lib/python2.6/dist-packages
checking for python extension module directory... /usr/lib/python2.6/dist-packages
configure: creating ./config.status

correct behaviour is not to expand the variables and keeping the ${prefix} and ${exec_prefix} macros
