FreeBSD tends to have everything needed, and the need to run pre-install commands is less common.
Custombuild does require gmake, but will try to install it with dpkg -r or ports if it's missing. If needed:
pkg_add -r gmake perl wget bison flex gd cyrus-sasl2 cmake python autoconf libtool libarchive
FreeBSD 10
pkg install gcc gmake perl5 wget bison flex cyrus-sasl cmake python autoconf libtool libarchive iconv bind99
