I forgot to mention in my quick reply:
If you are coming from Pd-extended, Pd vanilla does not include all of the
myriad external libraries that Pd-extended did by default. There is, however, a
simple package management system ("deken") which allows you to download and
install pre-compiled external libraries. This is what IOhannes pointed you to
with "Find externals."
Pd vanilla does not auto-load external libraries found within its search paths
by default. Pd-extended did, hence included libraries like "Gem" worked without
having to explicitly load them. Since Pd vanilla has no way of knowing what is
there and what is not, the [declare] object is used to explicitly add search
paths and load external libraries from a main patch. This is a similar
mechanism to "include" or "import" in programming languages. It's an extra step
but it helps ensure that it's obvious which libraries beyond the Pd vanilla
core object set are required to run you patch.
Thus [declare -lib Gem] tells Pd to try and find an external library called Gem
and load it. You may need the latest Pd vanilla release version for the to work
correctly as there was some recent work with how libraries are searched and
register their location with Pd.
