Out of curiosity, do previous versions work under wine?  I "wine" some dev poser tools.  Not for Linux but for Mac.

Same here.  99% Blender on Mac with a runtime that fits your description.

There's a bunch of animation stuff pipelined over the next few years in Blender that will be cool.  I expect that within 2 years, it will be possible (possibly even relatively easy) to "skin" Blender into Poser.  Imagine Poser using Blender native files.  Mmmmmmm.  So far, using Poser legacy content in Blender is difficult, though.  Hoops within hoops.

I've written a Blender poser mesh add-on, that makes it easy to go back and forth with morphs.  But that's as far as I go.  I've considered writing some code to bring Poser characters directly from a file into Blender.  I hit resistance on translating weight maps and shelved it as "meh" since I have a lot of other things on which to spend my time :)
