There is a difference between Lazarus and FPC finding it...

1) Do not copy the files from the SynEdit package to your path. never ever.
2) Do not add any -Fu -Fi or other custom path to your project, that 
points to synedit...

- In "project inspector", SynEdit is present as package under dependencies?
- Make sure you have only one version of FPC. As soon as 2 versions 
(even minor versions, even svn revisions) of FPC get's mixed, things go 
unexpected....
- Make sure, nowhere in your project, or in any path that you may have 
added yourself to the project, is a synedit.ppu (or any ppu for 
synedit*, except your highlighter)
- Compile with -va (and look add all+hidden msgs) to see where fpc looks 
for the file, and why they may be rejected. (a lot of output in msgs)

I assume you create the new highlighter in code? As it is not 
registered, you can not ue it on the form designer. (nor put it by hand 
into the lfm)
