[Scons-users] setting tool collection and compiler version from OS to OS

[Roger Martin]

William,

Hmm so I need to discuss with them about their scons scripts.  Not that 
I want you to bother with their build(it's in a state of repair and I 
have to find and pull all the parts) 
http://cctbx.sourceforge.net/current/installation.html.  Their build 
line actually starts with their own python and internally invokes scons.

/your/choice/bin/python ../sources/cctbx_project/libtbx/configure.py mmtbx

When building via jenkins I was hoping not to learn what all they're 
doing in there.

Thank you, I'll note to them about their script going with /usr/bin/c++ 
on Mac OSX.

Roger
