The subset (!) of the CCP4 5.0.2 libraries that we need for the cctbx
is included in in the cctbx bundles here:

http://cci.lbl.gov/cctbx_build/

A standalone tar file is also available, e.g. a specific version:

http://cci.lbl.gov/cctbx_build/results/2007_05_29_2026/ccp4io_502_cci.tar.gz

Or the current version:

http://cci.lbl.gov/cctbx_build/results/current/ccp4io_502_cci.tar.gz

BTW: We cannot redistribute the CCP4 6 libraries because of an
indemnification clause. Being at a government lab, it is virtually
impossible to get our lawyers to accept this clause.

CCP4 offered a click-through license to "pass on" the indemnification,
but that would have been more work technically than maintaining
the older LGPL'ed libraries, and it would make the cctbx a lot less
attractive for others, since everybody would have to deal with the
indemnification clause when redistributing the cctbx as part of
another package.
