[PD] Pd Gem versions summary

Some more clarification is needed when making a deken search for Gem
on OS X 10.6.8 with a 32bit kernel from within 64bit Pd. I am not even
sure if this very constellation is possible.

Deken lists 
    Gem/0.94 (deken-archive for macOS Intel/64bit (macOS10.12+))
    Gem/0.94 (deken-archive for old OSX>10.6 PowerPC/Intel32bit/Intel64bit)

Is the first one for versions larger than 10.12 only and the second
one for all versions up to 10.6.* ?

On my 10.6.8 box the first one does not load with a dlopen error. The
second one loads, so I assume that it is for OS X 10.6.* and above.

But is this latter Gem binary 32 or 64bit? I only found out it is a
Universal Binary.

...scratching my bald head...
