Hello, 

building LO 6.1.4.2 using “../configure --enable-evolution2 --enable-avahi --enable-python=system --enable-eot --enable-
online-update --enable-introspection=yes --without-doxygen --with-jdk-home=/opt/jdk --with-ant-home=/opt/ant --without-
junit --enable-formula-logger --enable-introspection --with-system-bzip2 --with-system-cairo --with-system-epoxy --with-

lcms2 --with-boost --with-system-nss --with-system-graphite --with-system-harfbuzz  --with-system-openssl --with-system-
libpng --disable-firebird-sdbc --disable-gtk”

fails with the error message below.
