[Freeswitch-users] svn up then make current - Errors

Hello, Trying to update the svn source. svn up make current I got the following Errors. cd libs/openzap && autoconf configure.ac:9: error: possibly undefined macro: AM_INIT_AUTOMAKE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. configure.ac:14: error: possibly undefined macro: AM_PROG_CC_C_O configure.ac:41: error: possibly undefined macro: AC_PROG_LIBTOOL configure.ac:119: error: possibly undefined macro: AM_CONDITIONAL make: *** [libs/openzap/Makefile] Error 1 How to fix the make error. Thanks Lloyd
