Does anyone know of a syntax highlight for Mako templates for Eclipse or for TextMate?
I know that there is a .mako syntax highlighter for the default text editor in Ubuntu.
You can go to:

Preferences->General->Editors->File Associations.
Click to add a new file type and type *.mak and click OK.
In File types click on *.mak and under Associated editors add HTML editor(default), Text Editor, Text Editor(studio) and Web Browser.

This colors the text, works OK for me :)
P.S. Be sure to have the Aptana plugin installed.
