hi stefano,

i stuffed the warning into google and it looks as if this
originates from incorrect linking, e.g. by trying to link
a static library as dynamic. without digging too deep into
the technical details it looks as if this would happen when
an old x86_64 compiler executable would be used on a too 
new installation or similarly related software that may mess
with dynamic and static linkage of libraries (e.g. MPI).
the error shows up on a large number of quite unrelated
software packages.

it is essentially a user error... and it has to be taken seriously 
since the affected functionality will not work. with large libraries 
like MKL it is impossible to predict whether some low level 
function is needed or not. if the calculation continues it would
be worse than getting a straight crash as one cannot know whether
there is some data corrupted or operations not performed and thus
the resulting data dependable or not.

cheers,
   axel.
