current status of migration

wait ... wait for commit approval
source ... f90/f77 sources exist
link   ... only exist link against f90/f77 complied libraries
gfortran ... used compiler is gfortran42 
f77     ...  used compiler is g77 (there are some compilation problem with gfortran)

--------------------------------------------------------------------
many are not yet done...

here is the newest tip

* Migrate to gfortran42
WANT_FORTRAN=yes #dummy but future use
BUILD_DEPENDS+= gfortran42:${PORTSDIR}/lang/gcc42
FC=	gfortran42
F77=	gfortran42
* Linking blas/lapack or atlas
.if exists(${LOCALBASE}/lib/libatlas_r.so) && !defined(WITH_BLAS)
WITH_ATLAS=     yes
.endif
.if defined(WITH_ATLAS)
LIB_DEPENDS+=   atlas.2:${PORTSDIR}/math/atlas
BLAS=		-lf77blas -latlas
LAPACK=		-lalapack
.else
LIB_DEPENDS+=   blas.2:${PORTSDIR}/math/blas
LIB_DEPENDS+=   lapack.4:${PORTSDIR}/math/lapack
BLAS=		-lblas
LAPACK=		-llapack
.endif

* Useful for other stuffs for gfortran related libaries when link against -lblas with C/C++ programs 
this corresponds to when some program want to link against libg2c of libf2c with GNU f77.

FORTRANLIBDIR=  `${DIRNAME} \`gfortran42 -print-libgcc-file-name\``
FORTRANLIBDIR2= `${DIRNAME} \`gfortran42 -print-libgcc-file-name\``/../../../
FORTRANLIBS=    -lgfortranbegin -lgfortran
