that message about lpeg is just there because the main scite binary has 
no lpeg

the lpeg lexing is using a library from scintillua which comes with 
textadept (that also uses the scintilla editing component)

it's a bit annoying that this small lpeg lexing extension is not part of 
sciet itself nor that scite has lpeg on board (in which case i could 
probably make the lexers use that)

in fact, even the scintillua code was a moving target that i redid the 
lua code to a large extend to suit my needs and another unfortunate 
aspect is that there is no real connection with scite's other propertie

so ... this is what i do (maybe i should ship a zip with all binaries too):

- install scite on windows
- also install the scintillua lib
- copy context stuff over it
- adapt the global or user properties file

this is described in the manual in the distribution btw.

- on linux i just use wine with the above
- on osx we never manages to get the combination working

so ... when i have time (or motivation) i might look into a way to 
enable/load lpeg in scite itself (should be doable i guess)

an alternative is to use textadept ... context comes with files that can 
be used for that (it simply replaces some text adept files and creates a 
context specific instance) .. on my windows:

start textadept -u c:\data\develop\context\textadept\data\context\

(running from the editor is then somewhat more clumsy)

on linux something

textadept -u <texroot>/texmf-context/context/textadept/data/context/

should work (hans that textapdept didn't change much in the meantime)
