I have got the trunk version of FreeSWITCH, have run bootstrap.sh, but I get get stuck in configure, where I get the following message, which I don't know how to act on: ./configure: line 13837: AX_COMPILER_VENDOR: command not found configure: error: Please update configure.in with SOLINK values for your compiler Versions: Freeswitch: build 9609, automake: 1.10.1, autoconf: 2.61, libtool: 1.514 or 1.5.24. Operating system is CentOS, uname -r = 2.6.9.-67.0.4.plus.c4 or 2.6.25.9-40.fc8 (same problem on two different systems). What should I do? Jon
