1) If it looks right to me there are 3 ways to determine paths and
libs on OSX and i am not quite sure if i am doing something wrong
or if it just has not been considered.
You can change the settings in the TCL-Interface of PD, but there
are not enough lines, to see all the necessary entries, in the /
Library/Preferences/org.puredata.plist file and vie a.pdrc file.
They do not really interact, i mean if you change something in the
pdrc file it is not written in the org.puredata.plist file, right ?
Yes, if you add to a .pdrc the changes will not be updated in the
org.puredata.pd.plist. You can either edit the plist file manually
(with the plist editor that ships with Xcodetools or with a text
editor (and needed be the CLI tool called plutil that can convert
between plain text and plist)) or add things to it via the panels in
Pd. For the later see:
By the way there are two gcanvas-externals. One in "ggee" and one
in "flatspace"...is that good ?
