[Ipopt] Compiling error

Hi Ismael,

These are missing Fortran runtime library symbols.  The strange thing is 
that the command line (g++ ...) does not include link flags for a Fortran 
runtime library.   Please make sure that you have a Fortran compiler 
matching your g++ and gcc installed, and that there are no error messages 
related to the Fortran compiler or the detection of the Fortran runtime 
libraries in the configure output.

Somewhere you should have something like

checking for Fortran libraries of gfortran... -L/usr/lib/gcc/i386-redhat-linux/4.1.2 -L/usr/lib/gcc/i386-redhat-linux/4.1.2/../../.. -lgfortranbegin -lgfortran -lm -lgcc_s

Hope this helps,
