[KDE/Mac] How can I change one piece of code in a MacPorts installation?

[Nicolas Pavillon]

Hi, 

Marko already covered several things, but I just would like to add another approach which has been helpful to me sometimes. The local repositories are a very useful way to patch up code, but in the case you have several tests to make, it can be pretty cumbersome, as you have to rebuild everything from scratch each time, with your new patches. 
Another way to avoid rebuilding everything is to use lower-level Macports commands, to avoid the fact that a new clean copy of your gets extracted each time, with a clean at the end of the install. You can run “port extract” to get a copy, change the code with patches or manually, and then run “port activate” to install the port, but normally without the cleaning stage, so that you keep the copy of the code.

Cheers, 

Nicolas
