Bugzilla Bug 114260

Current ~x86 ghemical requires openbabel 1 (not stated in DEPEND, but it fails
with openbabel 2), xdrawchem-1.9.9 requires openbabel 2. It would be quite a
PITA to install both openbabel versions parallel, I think. Ideas?

new openbabel

ebuild for openbabel-2.0.0

for xdrawchem, just copy over the 1.9.8.ebuild and update the required
openbabel
version to 2.0.0.

Possibilities:
1) Slot openbabel
2) Make ghemical and xdrawchem block (doesn't make any sense, people want both)
3) Update ghemical to be compatible with openbabel-2

I suppose a 4th options is moving (lib)ghemical 1.90 to ~arch, but it probably
shouldn't be going stable so I'd rather not do that.

Perhaps an idea for the library, but I don't like the idea of having two
parallel versions of the command line tools with symlinks to the currently used
version and all that stuff just for a package that is used for exactly _two_
other packages (IIRC).

Perhaps 2.5) make them block until ghemical is updated?

Even the latest development version, still not in portage (1.91), depends on
openbabel-1 so that might be a long time.

openbabel-2.0.0 with blocker for ghemical

I'm working on an ebuild for gnome-chemistry-utils, which needs this package. I
added a blocker for ghemical (which doesn't work on amd64 anyway).

ghemical-2.0.0 has been released and is compatible with openbabel-2.0.0
(preferably 2.0.1 since many bugs were fixed) and it works on amd64 :-)

Please see my submitted ebuilds <a
href="http://bugs.gentoo.org/show_bug.cgi?id=132835">Bug #132835</a>

openbabel-2 and ghemical-2 are now committed, so the new xdrawchem can get
added.

Fixed.
