version 4.3 of dakota is not yet released. The 4.3 version here refers to the VOTD release on May 12th 2009. While waiting for 4.3, we consider the develpment version to be 4.3. 4.2 is replaced by 4.3, to handle fnEvalId extra arguemnt to the Dakota structure. Be sure to set FC and F77 variable names to point to your fortran compiler, otherwise, the LHS packages will pick up gfortran as its fortran compiler, which can create serious troubles.
