[TxMt] ruby not found error

Hello all,

Stupid question here...I have:

ruby /Users/dc/Documents/txt/scripts/todo2log.rb $TM_FILEPATH

as a command, but it has suddenly stopped working, saying:

/bin/bash: line 1: ruby: command not found

the script:

#!/usr/local/bin/ruby

task_text = $stdin.read task_text.gsub!("\[ \] ","[X] ")

from = File.basename(ARGV[0],".txt")

File.open("/Users/dc/Documents/txt/LOGS/ completed.txt",'a'){|archive_file| archive_file.puts archive_file.puts task_text archive_file.puts " in #{from} #{`date "+%H:%M %Y%m%d %a"`}" }

ruby is to be found there (/usr/local/bin), and it worked yesterday, so I can't tell at all why this is happening...

but I know I'm missing something obvious

hints?
