[plt-scheme] Re: A segmentation fault on OS X Intel

I'm on 10.5, Intel.  I've checked the header file against the linalg
code and it is correct:

less /Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/Headers/cblas.h

...
   enum CBLAS_TRANSPOSE {CblasNoTrans=111, CblasTrans=112, CblasConjTrans=113,
                         AtlasConj=114};


less ~/Library/PLT\
Scheme/planet/300/372.1/cache/wmfarr/plt-linalg.plt/1/5/blas-lapack.ss

...

 (define _cblas-transpose (_enum '(no-trans = 111 trans = 112
conj-trans = 113 atlas-conj = 114))
)


I think the error must be either in Apple's CBLAS or in the FFI.
