i guess nobody ever tried...

anyhow, the "INSTALLATION" instructions of the glshim library explains
how to trick Gem into using glshim: you have to set the
LD_LIBRARY_PATH variable, in order to make Gem find the new functions.
you probably SHOULD NOT make this a system-wide (or even user-wide)
default, but instead only do this for when trying to start Pd/Gem (or
another application that needs GL1-on-GLES)

   LD_LIBRARY_PATH=/path/to/glshim/src/ pd -lib Gem

(you could also create a wrapper script that does this for you).

anyhow, Gem will also need GLU.

and there is the little problem that Gem will (by default) create a
window using GLX (on non-w32 and non-osx), which i think is not
available on android either.
luckily the git version of Gem has alternative windowing code (still
highly experimental), e.g. using SDL or GLFW, which  might work.
