>Description:
The current build of octave 3.6.1 doesn't use the newest version of lapack, so it crashes whenever using svd ( a VERY important math operation)

1> svd (rand(1,3))
 ** On entry to DORGLQ parameter number  5 had an illegal value
error: svd: exception encountered in Fortran subroutine dgesvd_

>How-To-Repeat:
Run octave

call "svd(rand(1,3))" from the terminal prompt.


>Fix:
An updated lapack needs to be used.  I am not sure which exactly, but I built from trunk recently, and octave worked when I compiled against it.
