how to build ledger more quickly ?

[Simon Michael]

 https://gist.github.com/931584 (ignore the pseudo shell test syntax)  
shows a bug in my version of ledger, 3.0.0-20100615. I knew I should  
test with the latest before reporting this. But building ledger takes  
entirely too long on my macbook, for this kind of side quest. John, is  
there a quicker way to build than just "make" ? I don't need ledger to  
run at its top speed (not at all), I'd rather optimise the compile time.
