alexispaz [1] filed a request to merge avogadro-git [2] into avogadro- git-eigen3 [3]: avogadro-git-eigen3 is updated and does not request all the dependencies of this package. Furthermore, this package uses the 1.2 version tag that has a well reported bug, an error on building (https://github.com/cryos/avogadro/issues/836), fixed in the avogadro- git-eigen3 version. Thus, even 1.2 is the last tag in the repo, this version is not stable as the last commit.
