I notice that /lsst/lsst_root_old/Linux/external/visionWorkbench/1.0.1/include/vw/Math has the package that I need for SVD installed, LinearAlgebra.h. I will try to use it while they are trying to get it in the new build system

becker550: eups declare -r /lsst/lsst_root_old/Linux/external/visionWorkbench/1.0.1 vw old
  ERROR : Cannot read required table file "ups/vw.table". at /lsst/lsst_root_new/eups/latest/bin/eups_declare line 186.

Ah, no directory ups/ there. Try this.

becker555: cp -r /lsst/lsst_root_new/Linux64/external/vw/1.0.1/ups /lsst/lsst_root_old/Linux/external/visionWorkbench/1.0.1/
becker556: eups declare -r /lsst/lsst_root_old/Linux/external/visionWorkbench/1.0.1 vw old
becker557: setup vw old
becker558: eups list | grep vw
  vw                     1.0.1                     Current
  vw                     old                       Setup

Cool, try it!

Bang!

It compiles dead on! Time to test it...
