[Numpy-discussion] Calling LAPACK function dbdsqr()?

Hi all,
I'm porting some Fortran code that makes use of a number of BLAS and LAPACK functions, including dbdsqr(). I've found all of the functions I need via scipy.linalg.lapack.get_lapack_funcs/get_blas_funcs() except for dbdsqr().
I see that the numpy source code (I looked at numpy-1.6.0b2) contains dbdsqr() in numpy/linalg/dlapack_lite.c, but grep can't find that string in the binary distribution on my Mac nor on Linux. If it's buried in a numpy binary somewhere, I'm comfortable with using ctypes to call it, but I suspect it isn't.
Can anyone point me to a cross-platform (OS X, Linux & Windows) way I can call this function?
I'm unfortunately quite naïve about the math in the code I'm porting, so I'm porting the code blindly -- if you ask me what problem I'm trying to solve with dbdsqr(), I won't be able to explain.
Thanks in advance for any suggestions,
Philip
