Hi, I sent this query over to the Rails list, but no joy there.

In general, how do you apply a patch to an installed gem? Do you have  
to get the gem src and rebuild the gem, then reinstall? Or, since it  
is just ruby code, can you apply it in place in the gem’s library  
folder.

I am specifically talking about the patch Ticket #2245:  
as\_clean\_logger\_rb-fixed.patch.  
which fixes the Rails 0.13/Ruby 1.8.3 Logger problem.

Thanks  
Ed

Why not just fix what’s broken and release a new version?

If this is just for you, then just change the code in the gem’s lib  
folder.
