strange: I still get errors when trying to access it - maybe only 
developer CVS is down ? John, are you able to access it ?

configure already tests for wxSTC... didn't you get a message 'wxSTC 
could not be found etc etc' ?

It does not disable it automatically if not found for choice: wxSTC is 
required for both wxLuaApp and wxLuaEdit applications... if you don't 
have wxSTC then you miss two nice apps ;)

this is sure a big problem - thanks for reporting it.
Fixed in CVS (wxluasetup.h was erroneously installed into 
$PREFIX/src/wxbind/setup instead of $PREFIX/include/wxbind/setup)

this was not to pollute the compiler line with a lot of include paths 
(we would need one for each subfolder in modules\ ...).

these last two are meat for John, I think ;)
