MATLAB: MATLAB R2012a LAPLACK BLAS load error Mac OSX Lion

blascrashlapackmacMATLABosx

I just installed MATLAB R2012a on a relatively new MacBook with OSX Lion. Install and activation was clean. The first thing I tried to run was "bench" in order to verify the install. I was surprised when bench crashed with the following error:
libmwlapack: load error: dlopen(mkl.dylib, 1): no suitable image found. Did find:
/Applications/MATLAB_R2012a.app/bin/maci64/mkl.dylib: truncated mach-o error: segment __LINKEDIT extends to 21094872 which is past end of file 21094672
/Applications/MATLAB_R2012a.app/bin/maci64/./mkl.dylib: truncated mach-o error: segment __LINKEDIT extends to 21094872 which is past end of file 21094672

Caught "std::exception" Exception message is:
dlopen(mkl.dylib, 1): no suitable image found. Did find:

I have tried reinstalling twice, once with a minimal install (custom install option, selected only MATLAB and Simulink) and once with all of my toolboxes (typical install option). So far, no luck getting past this error.
Some of my m-files will execute, but any dependent on BLAS or LAPACK fail with a similar error as above. I have no MEX-code (although I'm not sure what bench uses).
Hope someone out there has an idea on what is happening here!

Reinstalling from a web-based download versus the ISO solved the problem.
