If EMBed is GPL, then impem should be a separate lib, but at least it  
should be built and installed along with everything else if embed is  
available.

Why is it under different licensing anyway?

I added it since the script got the python version wrong and tried to  
install things in the 2.4 directory even though it ran python 2.5.  
Again something that will go away. At this point I've stopped using  
python and swig for my work and on my mac as it makes debugging too  
difficult and takes ages to compile.

Most people who build it will only build once, so config.py doesn't  
really help them. I have a makefile, which does more or less the same  
thing (I have a bunch of different build commands).

Summary of my emails:
- Normal people should not have to type more than
  scons install prefix=path [here are some extra places to look for  
libraries]
  to get absolutely everything that can be built built.
- And the fewer separate pieces which can exist or not exist  
independently of one another, the
  few things we can mess up with the install script (like the problem  
with mac os paths in modeller
  I ran into a while back) and the fewer things things the user can  
screw up (such as by not adding
  -limp-somethingoranother in the right order when trying to link a C+ 
+ program).
