Which computer are you running fluorescence on? Windows, Linux? Which graphics
card are you using, and which driver? (There is a known problem with the
nouveau driver on Linux)
This message does not necessarily mean that your hardware is not powerful
enough, but is due to a check for the opengl extension GL_EXT_gpu_shader4 that
is used in the shader. It could probably be rewritten to not require this
extension, but as it provides some very basic additions to the shading language
(e.g. proper integer support) I thought it was available on most computers
anyway.

Sorry for the laaaaaaaaaaate answer, anyway I tested it in three windows
machine and in a linux machine, except for one, that mounted a NVIDIA capable
of shading, the other video cards didn't have the shader so weren't capable of
running it, since the opengl driver wasn't updated for what was necessary, the
NVIDIA one instead had the necessary driver, almost same machines, but only
video card different.
The three machines were one SAPPHIRE, one ATI RADEON (I know, it's old, but
that was for testing purposes), and a little netbook that doesn't mount any
significant video card. The linux version was run on the ati radeon portable
computer. Don't ask for specific video version, and I guess I should re-test
now, if you changed something specific to this functionality in the meantime.
