it is:

at least i understand it as "binary compatibility".
probably it means something else.

there a nice command like uninstall ffmpeg? I installed it via-yum with
freshrpms or a similar repo... I imagine i could do without mpeg3 to.

to read mp4s i just need quicktime right?

depends on which codecs come with your installation of libquicktime.
it should work though.

yes, this is implied.

wait.
which libraries is Gem linked with?
try "ldd /path/to/Gem.pd_linux"
and/or create a [pix_film] object and observe what it says.

actually it is simple:
% ./configure --help
...
and then something like
% ./configure --without-ffmpeg

i thought that ffmpeg was disabled by default in the current HEAD of Gem 
which would make this unneccessary...i'll doublecheck

for theffmpeg error see above.
the mpeg3 error seems to be because fc8 stores the mpeg3-headers in 
/usr/include/mpeg3 rather than directly in /usr/include/ and does not 
provide a pkg-config option to detect this...

anyhow, just add another "--without-mpeg3" to the configure options.
