Issue in building iso 2.2.6

[bhawk6901]

I built an iso 2.2.6. Everything went well but when i invoke the install option get the error

"scripts/lua_installer: command not found"
Following are the steps i took

1. git clone -b RELENG_2_2 git@github.com:pfsense/pfsense-tools.git tools

2  ./set_version.sh RELENG_2_2_5 https://github.com/freebsd/freebsd.git
3.  ./build.sh –build-pfPorts

4.  ./build.sh iso --no-cleanrepos

Can any one please guide me if i missed anything? i shall be grateful
