[Fink-beginners] How to Modify (hack) Packages

[Rich J. <rjo...@do...>]

Hi folks--

How do I modify and install a fink package so that subsequent 
update-all doesn't overwrite the modifications?

If you must know, I want to change:
#ifndef MAC_OS_X_VERSION_10_3
to
#if !defined( MAC_OS_X_VERSION_10_3 ) ||  ( MAC_OS_X_VERSION_10_3 > 
MAC_OS_X_MAX_VERSION_ALLOWED )

to enable compilation.

Thanks,
--rich
