You need this software to build cvs source (in addition to normally required):
- autoconf 2.50 (tested with 2.57)
- automake 1.5 (tested with 1.7)
- libtool 1.4 (tested with 1.4.2a)
- gettext 0.11 (tested with 0.11.5)

It may or may not work with different versions. Autoconf 2.5 is required at
least anyway.

To create configure script in clean cvs checkout, do:
shell$ make -f Makefile.am
This will call all needed programs in almost certainly correct order ;).
