I just compiled Freeswitch on a Kubuntu 7.10 system without any errors. :) However, when I want to start Freeswith (in /usr/local/freeswitch/bin): $ sudo ./freeswitch I get: Cannot lock pid file /usr/local/freeswitch/log/freeswitch.pid. :( (I also tested Freeswitch on a Debian system, and there it's ok)
