[Ipopt] Linux 64bit with gcc 4.3.1

Hi Fabian,

If there are problems with Pardiso, Olaf Schenk would be the best person 
to help.

Maybe those need -lg2c (in case they were meant to link with g77 3.*), or 
the fortran runtime libraries that are expected by your MKL version are 
not compatible with gfortran 4.3.1 (I'm assuming that you are using 
consistent GNU compilers).

I have been able to compile it, but I didn't use MKL.  You could try to 
see if you can successfully compile it with the netlib Blas/Lapack 
sources.

It might be helpful to look at the output of the configuration script 
(Ipopt/config.log).  If you want to show it to us, please open a ticket at 
the Ipopt project page.
