 I believe we may have a compiler problem with gcc42.
 
 I had a problem with scilab under both -stable and -current.
 
 I installed the port with the default make files.  I saw no errors
 during build/install.  Scilab failed at run time.  ports/116378 and
 earlier kern/116166 which was changed to ports.
 
 Math/scilab uses math/lapack and math/blas and builds everything with
 gcc42 and gfortran42. 
 
 All three ports were up-to-date as of yesterday.
 
 Running -stable,
 
 #  uname -a
 FreeBSD dv6000.tddhome 6.2-STABLE FreeBSD 6.2-STABLE #2: \

 I deinstalled scilab, blas, and, lapack.  I rebuilt them with the
 default system compilers, g77 and cc.
 
 The problem went away.
 
 Scilab uses two gfortran specific calls in
 routines/os_specific/getarg.c.  Fixing these and changing the
 makefiles fixed the problem.
 
 Scilab.  Changed Makefile to use g77, cc, c++
   USE_FORTRAN=	g77
   CC=cc
   CXX=c++
   F77=f77
 
 build lapack with g77
    USE_FORTRAN=g77
 
 build blas with g77
    USE_FORTRAN=g77
 
 Removed gfortran from
 /scratch/obj/ports/usr/ports/math/scilab/work/scilab-4.1.1/routines/os_specific/getarg.c
 By using the default call in the #if..else statement.
