I'm trying to reproduce this bug, but I can't. I'm using a Debian 7 virtual box, download libgda from git, checked out branch and tag for 5.0.3 version, but build works with --enable-gda-gi switch. No build problems.
How can I get same environment? Have you try with development version 5.0.4 from git repository? Or you just can work with tarballs?
