And I even remember, that it used to work that way. I can't say why
that was changed, but there aren't any libGL* files or links in
/usr/lib anymore (on my Ubuntu system and I guess that is also true
for debian systems).
If I look at any other executable that is using OpenGL, I can see that
it requires libGL.so.1 and that the dynamic linker resolves this to
the correct library (mesa, nvidia, ati, whatever).
ldd $( which structure-synth )
libGLU.so.1 => /usr/lib/i386-linux-gnu/libGLU.so.1 (0xb766e000)
libGL.so.1 => /usr/lib/nvidia-current/libGL.so.1 (0xb759c000)
[...]
Now the Squeak VM handles shared libraries the same as VM modules. It
uses some relative (to the location of the VM executable) and absolute
paths to actually check if a library file exists, before it actually
tries to load the shared library.
The following is the mambo-jambo that the VM pulls to find the OpenGL
library on my installation (and fails):
