ok. makes sense.

ok.

actually no, you shouldn't do that at all with Gem.
Gem will (well: should) automatically add the paths, once its gets loaded.
and Gem should load fine, since the name of the binary ("Gem.pd_darwin")
matches the directory it lives in ".../Gem/", and the directory the
Gem-directory lives in (Contents/Resources/extra) is searched
automatically by Pd.
what you MUST do is to *load* Gem, e.g. by putting a [declare -lib Gem]
into your patch, or adding "Gem" (without any further path) to the
"libraries" to be loaded at startup)

this confuses me. what's the "Scripts" path doing in here?
could you post a screenshot of where Pd says that it's installing there?

Pd shouldn't (i think that feature with deken in Pd-0.48 is really a bug).
Gem would, but it needs to be loaded first.

i'm not sure i can follow.
how did it warn you?
if you deleted all folders and Pd warned you about a missing folder,
this sounds an ok (and totally non-magic) thing to do.

I assume that Gem wasn't being loaded at all since I hadn't added the path yet, and that the graphics were just inconsistent.

well, [gemhead] and [gemwin] created fine because you *did* have the
path added (they are abstractions inside the Gem/ directory).
but [pix_texture] is an object that is built-into the Gem binary, so you
need to *load* the Gem *library* first.

cool.

i think much of the confusion i'm having is because you switched between
0.47 and 0.48 during the installation and deken (the Pd package
installer) changed a bit between the two versions.
