Hi FS Users, tl;dr; - removed macports, removed tree, pulled fresh tree = installed FS on OSX. Here is the longer version that had a bit of a pre-emptive whinge about libtool version mismatch. But we never got there - it worked! I'm in the process of re-installing FS on OSX (10.6.8). I have removed Macports to try and get this up and running. I re-bootstrapped and got this error: quiet_libtool: Version mismatch error. This is libtool 2.4, but the quiet_libtool: definition of this LT_INIT comes from libtool 2.2.4. quiet_libtool: You should recreate aclocal.m4 with macros from libtool 2.4 quiet_libtool: and run autoconf again. make[1]: *** [libfreeswitch_la-switch_apr.lo] Error 63 make: *** [all] Error 2 Removed the whole git tree just in case there was some left over junk. Pulled a fresh tree and noticed this remark during a fresh bootstrap arakis:freeswitch-git chrismylonas$ rm -Rf freeswitch/ arakis:freeswitch-git chrismylonas$ git clone git://git.freeswitch.org/freeswitch.git Cloning into freeswitch... remote: Counting objects: 185609, done. remote: Compressing objects: 100% (39208/39208), done. remote: Total 185609 (delta 143241), reused 181443 (delta 140035) Receiving objects: 100% (185609/185609), 77.85 MiB | 267 KiB/s, done.
