gmodule-2.0 not found while compiling

Question

I can't figure it out. I seem to have all deps installed, but I'm getting the following error while trying to compile ValaPanel on Xenial:

./configure

Will output:

-- Looking for RPMTools... - rpmbuild NOT FOUND

The libglib2.0-dev package is probably outdated. It provides file /usr/lib/x86_64-linux-gnu/pkgconfig/gmodule-2.0.pc where version is 2.48.2 and does not satisfy requirement for vala-panel build. I would suggest to update libglib2.0-dev by backporting package from newer version or manually.
