I am having this same problem.  I was talking offline with Mary about
this.  The library libifcore.a is a fortran library, not a C library.  In
Intel compiler versions 8 through 10 (didn't check back further), it is
not included in the C compiler.  One solution to this problem is to
replace the linker icc with "ifort -nofor-main".
