[Lapack] Why there are two different versions of CBLAS ?

The clas.tgz is coming from recoding the BLAS in C by hand.
The CBLAS included in CLAPACK is coming from an automated Fortran to C  
translation with f2c.
Could I get some more details about your problem?
What kind of machine/compiler are you using?
Were the CLAPACK BLAS testing running correctly or not?

It seems that they look quite similar, but they are not. SuperLU
produces segmentation faults with the CBLAS in the CLAPACK
but not with the CBlas routines available separately.

It tooks me full fives days to identify the problem in CBLAS.
