here is what i did in what order

script setup is to use do

source setup

#!/bin/tcsh
setenv prefix /opt/local
setenv PATH /usr/local/ada-4.3/bin:/opt/local/bin:$PATH
setenv LD_LIBRARY_PATH $prefix/lib:/usr/X11R6/lib
setenv LDFLAGS -L$prefix/lib
setenv PKG_CONFIG_PATH $prefix/lib/pkgconfig:/usr/X11R6/lib/pkgconfig:/usr/lib/pkgconfig
setenv C_INCLUDE_PATH "$prefix/include"
setenv CPPFLAGS "-I$prefix/include"
setenv LDFLAGS "$LDFLAGS -L$prefix/lib -L/usr/X11R6/lib -lgcc_s.1"
#setenv CFLAGS "-malign-natural"

note
       on ppc the -malign-natural is not allowed.
       PKG_CONFIG_PATH is enhanced so stuff can find freetype and other stuff

anyway here is the list (except where noted the configures are 
       ./configure --prefix=/opt/local
