Hello,
I'm using TextMate version 2.0-beta.8.3 on OS X 10.11.1, with the latest version of the LaTeX bundle. When I try to use the “LaTeX Symbol Based on Current Word” command, it rightfully complains of the lack to the config_helper.rb file.

Failure running “LaTeX Symbol Based on Current Word”.

LaTeX Symbol Based on Current Word:6:in `require': no such file to load -- /Users/angelo/Library/Application Support/TextMate/Managed/Bundles/LaTeX.tmbundle/Support/lib/Ruby/config_helper.rb (LoadError)
    from LaTeX Symbol Based on Current Word:6

Any suggestions?

Cheers,
Angelo
