Oh, I missed that one. Specified "a" when installing, but didn't see that one with "Option AllowAlpha". Now different problem occured

Hmm, it's probably because nearly all libs are ".so.17", including "libmgr.so.17" while it's looking for "libmgr.so.16". Sure, it can be "fixed" by creating symlinks but I'm pretty sure it shouldn't happen at all.
