[gentoo-dev] Feature Request: compiling debug + symbol install ebuild?

Hi,

	Recently I hitted a problem with valgrind which required me to re-compiled 
certain library already installed on my system.  This triggered some thoughts 
as to how could gentoo support a debugging scenario.  Has anyone though of 
something in this area?

	I'm thinking of something like emerge --with-debug libxml which would then do 
most of the same stuff as normal except that it would run ./configure with 
- --enable-debug or appropriate options to trigger the gcc -g flag and before 
cleaning up the temp/work folder from /usr/portage it would install in a 
debug folder the source file so that gdb could find the symbol when debugging 
the libxml compiled using that technique.

	The problem I hit is that I am unaware how gdb retrieve the source file.  
What path he looks for first etc, in order to install the source at the 
correct location.  Also great would be to have only the source installed and 
cleaning the rest (object etc...) unless someone set the maintainer autoclean 
to off.

Make a bug for this. I agree with your request.
