When I tried to emerge scilab I got the message there are no ebuilds to satisfy batik-1.8-r2 even though batik 1.9 is the stable version on the official Gentoo repos. Presumably this is related to the fact that the ebuild wants to get that specific version of batik even though in the CDEPEND there is a >= in front of the version of batik
Steps to Reproduce:
1.Add the overlay science
I got the message there are no ebuilds to satisfy batik-1.8-r2
As the CDEPEND mentions >= batik-1.8-r2 there should be no problem
I think some lines of the ebuild require the version 1.8-r2 of batik which is unavailable on the Gentoo repos and in some overlay.
The ebuild has to be rewritten to match the actual version of batik.
