what do you consider necessary?
it would be good to know this modifications so they could eventually be
incorporated (or at least: handled) in a regular build.

how are you compiling Gem? using configure/make or using xcode (question
to jamie&chris: are you using the autoconf build system? (so can we
expect it to work :) ?)

all of them are defined in pd. you have to link against pd.
for this, the build process has to find pd (when using configure, i
think there is an option to tell it, where to find pd)

this might be a bug.
for now, just delete the files Pixes/record* and Pixes/pix_record.*
(don't delete Pixes/pix_recordQT.* if you want to record to a movie)
