minisip trunk build error

[Juha Heinanen]

i also tried according to http://www.minisip.org/develop_build.html and
libmutil part went fine.  then libmnetutil configure ended up with error:

./configure: line 19802: syntax error near unexpected token `0.3.1'
./configure: line 19802: `AM_MINISIP_CHECK_LIBMUTIL(0.3.1)'
