why do you want to install the build tools?  that's another manual step
that nobody else is currently doing, so you'll going to have to maintain
it yourself when things change.

it fails to create a UNO service, which according to "git grep
com.sun.star.xml.sax.Parser | grep \\.component" is from
sax/source/expatwrap/expwrap.component, which according to git grep
"gb_Library_set_componentfile.*expwrap" is  sax/Library_expwrap.mk aka
libexpwraplo.so.
