> BUILD, INSTALL and INSTALL-CHECK
> I was able to build the package and successfully ran MADlib
> install-check against PostgreSQL 9.6.2.
> Issue: There is no obvious reference to the PostgreSQL libxml
>        dependency in dev documentation. The madpack install-check
>        has failures (see below) if "--with-libxml" configure
>        option is not specified for PostgreSQL.
>        install-check errors encountered due to PostgreSQL
>        configuration without "--with-libxml" option:
>          psql:/tmp/madlib.0UIPlZ/pmml/test/table_to_pmml.sql_in.tmp:73: ERROR:  unsupported XML feature
>          DETAIL:  This functionality requires the server to be built with libxml support.
>          HINT:  You need to rebuild PostgreSQL using --with-libxml.
>          CONTEXT:  while creating return value
>          PL/Python function "pmml"
> {code}
> Story
> As a MADlib installer, I want IC tests that use lib-xml to be skipped, so that my install is clean and I do not have to wonder if there is a problem.
> More:  if at PMML export is called that requires lib-xml, then it will fail with a run-time db error which is fine.  This is not a commonly used function.
> Acceptance:
> 1) madpack install succeeds and IC passes even tho PG does not have libxml installed
