[PD] how to get GEM working in Vanilla?

[rolfm at dds.nl]

@ IOhannes

no Gem-meta.pd in the downloaded versions from 
http://puredata.info/downloads/gem or from deken.

Vanilla 46.7 shows the same problem with Gem

to me it looks like the lib is found, but the creation of the objects 
fails.
for [gemwin] there exists a gemwin.pd in the lib: the object box is 
drawn like it is ok, but the 'content' cannot be created (list of errors 
in Pd-console).
for [gemkeyboard] there's no gemkeyboard.pd: the object box is drawn 
partially showing the creation failed.

Gem.dll and Windows 10 not compatible?
or is it just my system?
