[TxMt] My homemade bundle dialog boxes don't work anymore

[logista]

When I use a command that has this statement

    require "#{ENV["TM_SUPPORT_PATH"]}/lib/dialog"

I get an error:

    /tmp/temp_textmate.rl42pL:3:in `require': No such file to load --
/Users/barbara/Library/Application Support/TextMate/Support/lib/dialog
(LoadError)
	from /tmp/temp_textmate.rl42pL:3

I'm not a programmer -- I just used the example from the TextMate book
for the dialog box, and it worked until this last update to Version
1.5.6 (1414)

How can I fix this, please?

TIA for any advice,
Barbara
