libobjcryst requires newmat11.

Do not download PyCifRW, let easy_install download from PyPI.
Do not test PDFgui if not included.

Make sure diffpy.Structure gets tested.
Rename build scripts to use execution order prefix.
Script for building and installing all sources.

Needs patchelf section to make the bundle relocatable.
Ignore the target build directories.
Fix DataLoader URL.

DataLoader was moved to sansdataloader.
Package name is sansdataloader not DataLoader.
Add option to select what packages are build.
Script for resolving relative paths.
Avoid building boost_python with cctbx.

Also fix script alignment.
Add section for patching RPATH in the shared libraries.

This makes the installation relocatable.
Resolve Python Major.minor version in the pth file.

This makes the same pth file work with 2.6 or 2.7.
Use setup.py to install SANS packages.

SANS packages are broken when installed with easy_install.
Turn on xtrace to show each test that is run.
Avoid using :A modifier so this works in zsh 4.2.
Fix flipped logic.

Target directories should be created when list mode IS NOT set.
Remove offensive trailing whitespace.
Use "1" instead of "yes" for no_boost_python argument.

cctbx converts it with int.
Disable build of python extensions.

They are linked to the cctbx included boost_python, but I would prefer
to link with the system BP.  Will investigate on this later.
Avoid error when there are no cctbx extension modules.
