hi, people !
some update on the subject:
i looked around and found this GEM-shader dedicated github-space:
bingo ! all of those patches worked alright !
more important for anybody interested: it contains a very useful
abstraction called "pix_shader.pd" which makes working with glsl shaders
much easier !

i can think of two possible problems:
- line endings (CRLF vs LF)
- paths with spaces
i think i can rule out the latter - i have PD on running as a
"standalone" application on an extra partition with no-space paths. plus
all other files (images etc.) that are called with an "open" message in
the GEM glsl example patches load alright
i will give messing around with line endings a try

well, as i said i didn't find too many ...
the good thing about the aforementioned site is, that it contains not
only the glsl shaders but also PD-patches to dig deeper into the glsl
thanks for all replys, already helped a lot !
again, a call to the list:
a dedicated place that holds a collection of glsl shaders/examples
optimized for GEM (i.e. with help patches) would be great, and i think
the puredata.info/downloads section would be a good place to hold it.
if you know about other PD (GEM) dedicated glsl site or github space,
i'd be glad if you could post it.
