OK
I've removed both TextMate folders
in /Library/Application Support/
and ~/Library/Application Support/
and tried your suggestions. Here are the results:
echo $TM_SUPPORT_PATH/Applications/02.webdev/TextMate.app/Contents /SharedSupport/Support
ls "$TM_SUPPORT_PATH/bin"Builder.rb CocoaDialog-license.txt CocoaDialog.app CommitWindow.app Markdown-license.txt Markdown.pl play pythonCompletion.py pythonCompletionTest.py shelltokenize.rb source-highlight source-highlight-license.txt tidy tidy-license.txt
CocoaDialog --help/bin/bash: line 1: CocoaDialog: command not found
Very strange.
