well, that's in the openGL/-src, so that's why i proposed 
"--disable-openGL" instead of "--disable-Manips"

which just means, that there are several undefined symbols, but pd stops 
at the first one it finds (so when you get rid of the glUniform4iARB in 
Manips/ it then finds the glUseProgramObjectARB in openGL/)

yes, in theory this should be ok.
but feel free to rerun configure like "./configure --disable-ARB 
--disable-openGL --without-ffmpeg"
i really recommend to _not_ disable Manips (but otoh, that depends on 
what you want: if you need Gem only for reading quicktime and then you 
convert it to pdp (since pdp's quicktime is so broken), then you might 
well do without Manips; in this case you can also disable Particles, 
MarkEx, Geos, Nongeos)

what i sent to you is a patch file that contains the differences between 
  the original GemGL.h (hopefully yours) and a modified version of 
GemGL.h (which hopefully fixes some of your problems)

"try the attached patch", means that you should "apply" it, using the 
"patch" program ("man patch")

assuming that you downloaded the file to ~/GemGL.h-ARB.patch and Gem's 
sources are in src/Gem, this would mean something like:

  ~$ cd src/Gem/src/Base
  ~/src/Gem/src/Base$ patch -p0 < ~/GemGL.h-ARB.patch
  ~/src/Gem/src/Base$ cd ..
  ~/src/Gem/src$ make

the 2nd line holds the magic
