* bind: dropped buildessential dep
* elinks: added --without-x to avoid libx11; bumped version to f86be6597
* gnupg: changed dep "automake" to build stage only
* fixed flex's 410 error
* added serf HTTP library for subversion
* added scons build system
* updated subversion to depend on serf,
because in my infinite wisdom my
original build didn't include HTTP(S)
support
* added openldap. This does not include
slapd because I couldn't figure out
how to build Berkely DB4.
* added pacparser
