There is a new version out and the old ebuild works. Reproducible: Always Steps to Reproduce:
Just days after our last bump... ok, thanks for the hint. Will go into portage soon.
xdrawchem-1.8.2 is in Portage and works correctly, but there is a new version out (1.8.3), and it works with the current ebuild.
Yet another one, ok... thanks again.
