This is what I do:
    I have /Users/Shared/OpenSource/ where I put stuff like VTK, ITK,  
ParaView and such
    I have /Users/Shared/Toolkits where I actually have the  
installations of VTK, ITK, ParaView after they are compiled.

    Inside my home directory I have 'Workspace' which is an Eclipse  
CDT workspace where I have my own projects.

    Note that /usr/local is NOT by default created on a clean OS X  
installation. Some packages insist on putting things in there which is  
reasonably safe since it is NOT on the path. You will have to edit  
your .bash_profile to append /usr/local/bin to your PATH variable.

------- DO NOT PUT ANYTHING IN ANY OF THE FOLLOWING LOCATIONS ---------
/usr/*   (except /usr/local)
/System/*
/bin
/dev
/net
/private
/sbin
/Developer

    All of these locations should be considered OFF limits because  
Apple will at their own discretion put stuff or delete stuff from  
those locations WITHOUT asking you first or at least making it clear  
what they are doing. Just consider those areas as Apple's playground  
and you are not invited.

Fink and MacPorts use /opt and /sw to put their products into which is  
a reasonable good idea because Apple does not as of yet use those  
directories for anything so getting rid of Find or MacPorts packages  
is reasonably safe.

You can put your own items in /opt or /sw BUT those directories are  
not default on any OS X system which is why I like /Users/Shared/*  
because /Users/Shared IS by default created on OS X installations.

OS X _is_ unix and 'linux-like' BUT you don't administer it like a  
unix/linux machine.

I think for the correct audience Fink or MacPorts can be an excellent  
way to get software compiled and installed on your system. They have a  
clean approach to installation which is good.
