Ok, I finally figured out reason. When I configure with option:<br>
<br>
--with-blas-lapack-dir=/opt/intel/Compiler/11.1/072/mkl/lib/em64t<br>
<br>
PETSc doesn't find blas/lapack libraries there because actual names
are libmkl_blas95_lp64.a/libmkl_lapack95_lp64.a and (just my
suggestion) either automatically substitutes libraries from
somewhere else or uses just stubs without actual subroutines (as
Matt correctly suggested).<br>
<br>
Since 1 year I use petsc I've never come acrross this problem
because I always built with blacs/scalapack and used more than one
process in which case routines from blacs/scalapack libraries were
used.<br>

I tested various combinations, for the error. <br>
<br>
It appears only in this combination: <br>
<br>
* debugging configuration <br>
* MKL blas/lapack (but not blacs and scalapack!)<br>
* development branch <br>
<br>
The release configuration, reference blas/lapack installation or
petsc-3.2-p5 do not have the problem. <br>
