It seems they are not yet in the RPMs of the MariaDB repo for OpenSuSE. At least they were not 5-6 hours ago. But I am not in a hurry.

Hi, Peter!

But most important TokuDB plugin does not load. This may because this

See the error log, it might contain more specific error messages. One probable reason could be transparent_hugepage enabled on your computer.
BTW: I also had some communication on Fedora's mailinglist. They have MariaDB 10.0.14 in Fedora 21 repos. But without TokuDB. They cannot build it. They have reported to MariaDB (they say).
Yes, there were issues with TokuDB and gcc 4.9 (MDEV-6446, MDEV-6449), but they were fixed.
And there was binutils bug in Fedora (it resulted in crashes when compiling TokuDB): https://bugzilla.redhat.com/show_bug.cgi?id=1149660 As far as I understand, it's also fixed by now.
