chances are, that you (jack) did install the plugins into
/usr/local/lib/pd/extra/Gem and then started Pd/Gem from
/home/jack/src/Gem/src (wherein a Gem.pd_linux lives)

this won't work, because Gem searches for the plugins besides the Gem
binary it loaded.
so if it loaded /usr/local/lib/pd/extra/Gem/Gem.pd_linux it will search
in /usr/local/lib/pd/extra/Gem/ for plugins (which are named
gem_<type><name>.so, e.g. gem_videoV4L2.so).
if you loaded /home/jack/src/Gem/src/Gem.pd_linux, then it will search
in the src path (rather than the /usr/local/...)

the simple fixes are, either:
1) do a "make install" (so everything is in
/usr/local/lib/pd/extra/Gem/) and then make sure that you are using the
installed binary (e.g. by starting Pd in a new terminal)
OR
2) create local copies of the plugins besides the Gem.pd_linux you want
to use; i usually do symlinks:

~/src/Gem/src$ ln -s plugins/*/.libs/gem_*.so .
~/src/Gem/src$ ls Gem.* gem_*.so
gem_filmAVIPLAY.so  gem_filmDarwin.so  gem_filmGMERLIN.so
gem_filmMPEG3.so  gem_filmQT.so  gem_recordV4L2.so
gem_filmAVI.so      gem_filmDS.so      gem_filmMPEG1.so
gem_filmQT4L.so   Gem.pd_linux   gem_videoPYLON.so
