#Note: 
#     This installation example is based on a "Turnkey LAMP" appliance 
#     running on a VM. The same step should apply to a freshly installed 
#     debian/ubuntu.
#     If installing on a new debian/ubuntu, you will need to install and 
#     configure Apache2 and MySQL.
#
#
#Atfter finishing you LAMP installation:
#
#Prepare pre-requisites:

#We need the ESL module for perl, so compile it:

     cd /usr/local/src/freeswitch/libs/esl/
     make perlmod
     make perlmod-install (*)

     (*) If the "make perlmod-install" command fails with 
         "install: cannot create regular file `/usr/local/share/perl/5.10.1': No such file or directory"
         You need to edit /usr/local/src/freeswitch/libs/esl/perl/Makefile and set PERL_SITEDIR to perl's correct path,
         in my case it was PERL_SITEDIR="/usr/share/perl/5.10.1/", and execute again.
