[Kwintv] Sources from yesterday failed to configure (2nd)

[Sangohn Christian]

Maybe this is the real cause of the problem:

[xtian@sikasso:~/src/kdenonbeta] $ make -f Makefile.cvs
This Makefile is only for the CVS repository
This will be deleted before making the distribution

*** Creating acinclude.m4
!!! If you get recursion errors from autoconf, it is advisable to set the
    environment variable M4 to something including "--nesting-limit=500"
*** Creating list of subdirectories
*** Creating configure.in
*** Creating aclocal.m4
configure.in:79: error: possibly undefined macro: AC_CHECK_UNSETENV
make[1]: *** [cvs] Error 1
make: *** [all] Error 2
