Fast
fourier transform works (and a lot of things I have tested) where as
johansen-test does not. There is lapack in /usr/lib64 which is the same
as in the one in /usr/lib.
Lapack is working in R, and in test programs (R and c++).
Is your R binary in fact linked against your system liblapack? I
find that's not the case on my own system:
allin@myrtle:~/src$ locate lib/liblapack.so
/usr/lib/liblapack.so.3.0
/usr/lib/liblapack.so.3
/usr/lib/liblapack.so

Note no linkage to /usr/lib/liblapack.so: R seems to prefer to use
its own lapack implementation (built into libR, I suspect).
Allin.
