Variable replacement

[gtramontina]

Hey there,
I was writing the readme for one of our internal projects that is experimenting with gasket, and I used the pipeline example from here: http://blog.petersobot.com/pipes-and-filters

cat /usr/share/dict/words |     # Read in the system's dictionary.
grep purple |                   # Find words containing 'purple'
awk '{print length($1), $1}' |  # Count the letters in each word
sort -n |                       # Sort lines ("${length} ${word}")
tail -n 1 |                     # Take the last line of the input
cut -d " " -f 2 |               # Take the second part of each line
cowsay -f tux                   # Put the resulting word into Tux's mouth

Running with gasket, it failed like this:

awk: syntax error at source line 1
 context is
    {print length(), >>>  } <<<
awk: illegal statement at source line 1

Might gasket be replacing the variables wrongly?
Cheers!
