Since I am on a Centos5.8 (with old GLIBC) I have to rebuild the binaries from source.

The following were not compiling properly (either gfortran (4.4) or Intel compiler) since they still had the old date:
IDLbathy
IDLlandmask
IDLread_meris_bands
IDLswfmapbin
l2binmatch

I was able to compile them all by fixing the Makefiles except for l2binmatch (I compared the Makefile for Seadas6.3 with the present one):
IDLbathy: Enable first option in Makefile (in directory $SEADAS/build/c4idl/IDLbathy):
LLIBS   =  -lsdsgen -lgenutils
#LLIBS   =  -lgenutils
IDLlandmask: Remove hk from first line in its Makefile
IDLread_meris_bands: Remove jk from first line in its Makefile
IDLswfmapbin: Remove map from first line in its Makefile

I haven't been able to fix l2binmatch.  I couldn't find an error associated with it either in the .out log files.

At the end of the compilations it now says:
Total expected libs/bins: 19/44
Total existing libs/bins: 17/47

So there is a mismatch in number of libs/bins.  Not sure from which I have too many or am missing.

These are my libs (in $SEADAS/build/lib):
lib24to8.a  libbin++.a     libhdfutils.a  libmap.a    libosmi.a    libseawifs.a
libanc.a    libczcs.a      libl2.a        libmeris.a  libsdsbin.a  libswfnav.a
libbin.a    libgenutils.a  libl2_viirs.a  libnav.a    libsdsgen.a

And here are my bins (in $SEADAS/run/bin/linux_64):
date2jd              IDLswfl3pname       l1asubset_modis  l2mapgen
fixrgb               IDLswfmapbin        l1bgen           l3bin
geocheck_modis       l0chunk_modis       l1bgen_modisa    l3bindump
geogen_modis         l0cnst_write_modis  l1bgen_modist    l3binmerge
IDLbathy             l0fix_modis         l1brsgen         l3gen
IDLlandmask          l0info_seawifs      l1info           l3rebin_meris
IDLmodismapbin       l0merge_seawifs     l1mapgen         lonlat2pixline
IDLread_meris_bands  l0regen_seawifs     l2bin            pdsinfo
IDLread_meris_data   l1aextract_modis    l2binmatch       pdsmerge
IDLread_meris_dims   l1aextract_seawifs  l2brsgen         smigen
IDLswf2idlmap        l1agen_modis        l2extract        smitoppm
IDLswfangle          l1agen_seawifs      l2gen

Wondering what I am missing...  Below messages while building:
