  Verify the result if you run it manually:

  /usr/local/bin/buildDMG.pl -debug -buildDir=dist -compressionLevel=9 
-volName=BitPim -dmgName=JAGUAR-BitPim-0.26.dmg dist/BitPim.app

  It seems as though it's failing on:

  hdiutil detach $dev

  Unsure why, usually it's because some process (Finder? a shell cd'd 
into the image dir?) has it locked so it can't be removed.  When run 
with the -debug switch, you'll see the exact command it's issuing... 
Try that your self when it fails. Also, you can use `lsof` to see what 
has it open... you'll have to scan the output to see if you can find 
the process... I'd *guess* that the lock would be *inside* the mounted 
image, not on the image file itself, so maybe something like:

  lsof | grep /Volumes

  As a test, I opened a shell and set it's current directory to inside a 
disk image of buildDMG, and got this:

bash      1632 n9yty  cwd   VDIR      14,10       1024        2 
/Volumes/buildDMG (/dev/disk4s2)

  Anyway, that might give more useful information... Anything in the 
console log or system log?
