You may require the libguide from MKL (newer than the one from ifort 9.1) to find a version which is compatible both with ifort 9 and with MKL 10.1.  If you don't want MKL to start its own threads or have problems with OpenMP run time link compatibility, use the mkl_sequential library in place of mkl_intel_thread.  Then you should not have a problem with the libguide chosen by ifort 9.1.   These problems should be alleviated by ifort professional (all recent versions), where the current MKL is included in ifort.
