alrighty, i tried, failed, and resorted to asking for advice on the 
swipl mailing list.
i got the following;
If you really want to go minimal, just install "SWI-Prolog lite", as 
described in the link I posted above:
http://eu.swi-prolog.org/build/unix.html
Follow the instruction under "Doing it in multiple steps" and see if 
this is good enough.
If you use build.templ just add the package names you don't want to the 
DISABLE_PKGS variable. For example, to skip a bunch of things, including 
the GUI (xpce):
export DISABLE_PKGS="jpl xpce chr cql protobufs odbc ssl RDF semweb"
and so on. You can look under packages to see what are the names of the 
packages.

can i now approach the "ports" mailing list with a request to also 
provide swipl-lite?
